if i'm not mistaken, DB's restriction numbers were arrived at by revving the car in neutral. the numbers i'm coming up with are under max load. his OEM filter max was 4.8, whereas i got two different OEM filters to near 10. both sets of data are useful, but they're not not comparable.

OK. That is just too slick. You do have to bleed that filter at the plastic bleed screw, correct?

Did I miss the part number for the filter? I know where I can scavange a similar head, but I know from sad experience that the notches are different for different filters.

If I had the part Number and filter name, I could cross it to a Deere number and see if I have the right head.

Edit: OK, I see "Fuel manager" and "31873". is that correct? Do you have a different number such as a Fleetguard number or even a NAPA number would probably work.
from like 13 posts above... (way up there)

33462 - head unit with 4.3" 5-micron element (92% efficient at removing 2-micron and larger particulates at 45gph, 97% at 5-micron, 95% at removing emulsified water, 98% at removing whole (free) water): $33.20

31873 - 5-micron replacement element: $13.87

35160 - (optional) side mount 100watt/12volt thermostatically controlled fuel filter heater: $39.54
regarding bleeding - yes. but i didn't think of it at first. i'm so used to the lift pump quickly filling an OEM filter, that I tried starting it without bleeding and it ran but then stalled - between all the new lines and the dry filter it was just too much air to deal with. that's when i pulled the filter, noticed it <u>had</u> become full, reinstalled and it started right up.

you obviously have experience with this type of filter, what would be the ideal procedure for replacing filters & bleeding or for future new installs?

i don't know any cross reference part numbers - sorry.

Probably the way to bleed it would be to open the plastic bleed screwon the side opposite the mount, turn key to run, close screw when clear fuel comes out. Or, since it's a PD, you may just be able to turn the key on for a minute and let the tank pump run.

When I went to Langley, BC I saw somone with this type of filter installed. I don't recall who it was, though.

How To: Stanadyne 5-micron Fuel Filter Upgrade

Thanks very much for the write-up Sunrg!
Why did you choose to mount it in the front of the engine bay instead of the original filter area?
I think brass is not compatible with biodiesel (not sure if you run it but others that read this like myself may). Those people may need to find different fittings.
Thanks again!

the PD lift pump does not stay on when the key is turned forward, but you can pull fuse 28, connect 12v power and continuously run it that way. of course the slickest way would be to get the "hand priming pump" option... [EDIT: THIS OPTION SIGNIFICANTLY INCREASES RESTRICTION AND SHOULD NOT BE USED IN TDI APPLICATIONS]

Dweebus: Why did you choose to mount it in the front of the engine bay instead of the original filter area?
i don't think the filter would fit in the OEM filter area. i know for certain that you would not be able to change the filter element with it mounted in the OEM location. plus the fuel line routing is much more simple and direct where i've mounted it - and it's much warmer where i've mounted it, which should make cold weather performance even better.

Dweebus: I think brass is not compatible with biodiesel (not sure if you run it but others that read this like myself may). Those people may need to find different fittings.
this is news to me. i run biodiesel nearly exclusively. what type of problems should i expect with the brass?

PDiesloiler: Great write-up SUNRG....thanks. How about the thermal diverter valve tee heater for those that want to keep fuel heating oem-like?
yeah, that diverter is a cool option. i seriously think that if Stanadyne Performance Formula additive (or comparable) is used every tank in the winter, even the fuel heater is not needed. but, more insurance is more better - i'll look into it and post what i learn.

but, it is <u>amazing</u> how many cool options and add-ons are easily possible with the FM100! it'd be cool to add: <ul type="square">
[*]electronic water in fuel sensor
[*]hand priming pump
[*]see through water collection bowl
[*]and the one i have done, the electric fuel heater
[/list]every single one of these could be easily added to a TDI installation.

i drove on a 250mile road trip today, and the FM100 restriction level with the 5-micron element is higher than OEM. it appears that, like the CAT 2-micron setup, the FM100 with the 4.3 inch filter element produces about 40-50% more restriction than OEM. i've ordered the 6.0" 5-micron filter media and that may lower the restriction level slightly. since roughly 450 persons have the CAT system installed in their TDIs, and none have reported problem, my feeling is that this level of restriction increase not a problem. i'll post new restriction numbers when i have the 6.0" element installed (probably next Tuesday). what i have so far is:<ul type="square">
[*] OEM at full load = ~10"Hg
[*] 4.3" 5-micron FM100 at full load = ~14"Hg
[/list]Stanadyne does make 10-micron elements for the FM100, which anyone uncomfortable with the restriction increase could go with, but the 6.0" 5-micron is a large element that is used in much bigger engines than our relatively puny TDIs. it's rated at 80gph (roughly 4x the TDIs estimated 18gph flow rate, and 60psi which is probably 6x the pressure in our systems (on the suction side of the tandem pump). i repeatedly WOT accelorated to redline during many shifts today and there was no hint of fuel starvation. "normal" fuel demand is a small fraction of the fuel demand at redline and WOT. bottom line is that in theory, the FM100 is way more than adequate for our little engines.

the other thing to consider is that my restriction numbers only compare maximum restriction under the highest demand scenario i can create. comparing restriction while cruising at 75mph on the highway may yield little or no difference at all.

i'm very happy with the setup, and once i install the 6.0" element i'm not even going to think about fuel filters for a year or so
i may restriction test a 10-micron element if i can easily get a hold of one, but Reliable does not stock them.

the combination of the Stanadyne additive (SPF) and filter (FM100), and that they're engineered to compliment each other, makes me confident that the fuel reaching my engine is of outstanding quality.

it's important to note that the goal of both is to remove water from the fuel, <u>not</u> chemically treat it and send it through the system. the filter removes 95% of <u>emulsified</u> water and 98% of free water. an additive like SPF will improve the filter's ability to remove water even further, but i wouldn't recommend using additives like Howe's, Primrose, or FPPF with the FM100 filter, since they all chemically treat water with the intent of sending it past/through the filter and safely through the fuel system. i don't think there would be any harm in using them, but if your going to do the FM100 upgrade you may as well use additives that will help it do what it's designed to.

UPDATE:<ul type="square"> [*]electronic water in fuel sensor - #29268, list $104.70 (comes with all wiring and dash mount indicator)
[*]hand priming pump - <font color="blue">available, but it involves valves that will result in significantly increased restriction - so i wouldn't recommend it for our application (VW TDI).</font>
[*]filter change indicator - <font color="red">not currently available to aftermarket, potentially in 1-year.</font>
[*]thermal diverter valve - <font color="red">not available to aftermarket. demand is very low and will not likely ever be released to aftermarket.</font>
[*]see through water collection bowl - #29899, list $46.48[/list]when installing a new FM100 filter DO NOT PRE-FILL THE FILTER ELEMENT unless you are confident the fuel or additive is super clean, because the fuel would go unfiltered directly to your fuel pump.

it may not be necessary to do anything (priming or pre-filling of the filter element), but in PD, opening the bleed valve on the FM100 and then powering the in-tank lift pump via fuse #28 until fuel starts to come out of the bleed valve is ideal.

From biodiesel.org (http://www.biodiesel.org/pdf_files/fuelfactsheets/RegulatedFleet_QA.pdf)
Are there any materials compatibility issues with B20? If it comes in contact with brass, bronze, copper, lead, tin, and zinc for a prolonged period of time B20 will degrade and create sediments. Lead solders and zinc linings should be avoided, as should copper pipes, brass regulators, and copper fittings. Affected equipment should be replaced with steel or aluminum. The effect of B20 on vulnerable materials is significantly reduced compared to higher blends.
Not sure if this is really an issue or not. If you parked your car for the weekend and then started it up Monday morning, did a small amount of sludge form around the brass connector of the filter output that will go into the injectors? It's probably not going to cause issues, but...

Just got back from the local Stanadyne dealer and was quoted almost $58 for the head with 5 micron filter. I can't be sure the part numbers were the same, but it didn't have any of the addons attached to it.
Is your price the list price, or just what you paid?


33462 - head unit <u>with</u> 4.3" 5-micron element (92% efficient at removing 2-micron and larger particulates at 45gph, 97% at 5-micron, 95% at removing <u>emulsified</u> water, 98% at removing whole (free) water): $33.20

$33.20 is what you will play. if you buy a separate head unit and then a separate filter it will be a lot more. 33642 is both together - a complete assembly.

i've tried to find steel or aluminum 3/8"NPT > 5/16"HoseBarb fittings but have had no luck. let me know if you find something.

it turns out that the 6.0" 5-micron replacement filter element is less than $14 from reliable too

Nah... I'm just a Deere guy, so I gotta flick it to the Cat huggers out there when I can.

What's the advantage of the Stanadyne FM100 over the Cat unit? Price? efficiency?
there's advantages to each system. there's tons of info on the web and here regarding them, and you really have to decide for yourself which best suits your needs.

price: the basic FM100 setup will cost about $55, requires a trip to autozone and the hardware store, and requires some drilling and grinding. CAT is $115 but it's all inclusive.

2-micron efficiency: CAT probably wins vs the 5-micron FM100, but it's likely very close since the 5-micron FM100 stops 92-93% of 2-micron and larger particulates at a cranking 45gph.

stays true to OEM configuration: CAT wins. completely custom head exactly matches OEM functionality.

ease of install: probably CAT wins, though the FM100 install is very easy and straight forward.

replacement element cost: similar. the largest (best) FM100 cost $13 and some change from reliable, the CAT is $16 with o-rings from www.lubricationspecialist.com

water management: my guess is that the FM100 gets the nod here.

ease of element replacement: FM100 (it couldn't possibly be easier)

add-ons & upgrades: FM100

On the Stanadyne site it looks like hose barb fittings are an option:
Optional screw-in threads, OR metal hose barb/latch bead/ "quick connectors"
Contact Stanadyne for details
I did a little searching, and yes, that's a tough size combination. 3/8" > 3/8" would be much easier. I did find
one in plastic, but it didn't say what kind of plastic.

you could go with a bushing, say 3/8 > 1/4, then 1/4 > 5/16 hose barb - <u>or</u> - i bet 5/16 hose can be forced on a 3/8 hose barb. it's only a 1/16 difference!

Great write up!! you got me thinking seriously about doing this!

Also thinking about my father's boat. with twin Yanmars he uses more fuel than us TDI folks. better filtration, is simply better.

as for stainless barb and NPT fittings; here in Mass. I go to a place called "All Stainless" it's where I got a lot of hard to find stainless parts for the homebrewery (beer not BioD)

just try the Grainger or McMasterCarr catelogs. they should have those in stainless.

thanks for the write up

Update: Stanadyne 6.0\" 5-micron filter restriction

i replaced the standard 4.3" 5-micron FM100 element with a 6.0" 5-micron element today - and it appears that the larger element reduces restriction.

my restriction guage's drag pointer indicated that 12.5"Hg was the max restriction i have been able to get my FM100 to produce in the last few days (OEM filters maxed at ~10"Hg) - however after driving ~20 miles with the 6.0" element with a few WOT to redline shifts i checked the guage and restriction was below 10"Hg. i reset the guage, and again, drove home (another ~20 miles) and the guage was maxed at ~10"Hg.

over the next few days i'll drive 300-400 miles and should be able to confirm if these lower restriction numbers are legitimate or a fluke. if they are legit, and it does seem logical that a larger filter could result in less restriction than a smaller one with identical media, then the 6.0" element is a great replacement choice - and it's roughly the same cost as the 4.3 - under $14.

Re: Update: Stanadyne 6.0\" 5-micron filter restriction

Thanks for the update. I'd like to perform these tests on my CAT filter at some point future.

Wonder if these values would stay constant in cold temps or how the values would compare to stock?

gearhead - you can buy a drag pointer fluid restriction guage (vaccuum), and "T" it into the fuel line between the CAT or OEM filter and the engine. i did this with two OEM filters, that's how i know OEM max restriction in a PD-TDI is roughly 10"Hg (according to my guage). i tested both the old style (Mann/Meyle) and the new (Bosch/Mahle) and each returned roughly the same 10"Hg after repeated WOT to near redline accelorations.

i have to tell you that my TDI has been getting quite a workout recently! this is the 5th filter element i'm testing and i've repeatedly driven my TDI to produce max restriction - WOT to redline accelorations, shift after shift, many many times.

it's actually been a lot of fun, and so far i haven't got a speeding ticket. if they weren't before, my rings a certainly well seated now


note: for best acceloration, don't accelorate to redline. my experience is that shifting just after the needly crosses 4k yields the best acceloration. i'm just accelorating to redline because more fuel is used at WOT at redline than at 4k and i'm trying to absolutely max out fuel demand.

Re: Update: Stanadyne 6.0\" 5-micron filter restriction

I'm not finding a Deere filter to cross to that 31873 number. Found a Fleetguard number that we have in stock: FS19531. I guess if I could find what application we have for that filter, I could find the filter head that way.

Re: Update: Stanadyne 6.0\" 5-micron filter restric

Does anyone know the part number of the Stanadyne with a 6" filter element?

33462 is the part number witha 4.3" element.

Hi Herm,
I am interested in the Stanadyne 2 micron filter system. Which part numbers did you get for your kit (head, element, botom bowl?)?
Thanks
33462 - head unit <u>with</u> 4.3" 5-micron element (92% efficient at removing 2-micron and larger particulates at 45gph, 97% at 5-micron, 95% at removing <u>emulsified</u> water, 98% at removing whole (free) water): $33.20

31873 - 5-micron replacement element: $13.87

35160 - (optional) side mount 100watt/12volt thermostatically controlled fuel filter heater: $39.54
Are you sure about that part number for the head unit?
I call my local Stanadyne dealer and he could only find 33642? Maybe you swapped the 4 and the 6?

Also the price you have is MUCH BETTER.
I'm going to see if he can match your price if not I will be calling the Reliable guys.
