Default fm100 installed on the golf now

i just installed the same setup in my golf at 21500 miles. it went a lot smoother second time around.

the mann pre-filter doesn't have any nubs on it, and the smallest spring clamp i've found doesn't clamp hard enough i think. it leaked on my jetta. the smallest screw clamps i found got all ovally when tightened to that small diameter and also caused leaks. so for the golf install i wrapped the end of the hoses going into the pre-filter with electrical tape to add diameter and used the screw clamps there - works perfect and no leaks.

i also got the teflon tape done better for the NPT bards and side-load heater going into the fm100 head. first time i did it, i wrapped the tape the wrong way so as i screwed them in the tape starting bunching up, and would be a little leaky.

as for wiring up the heater, i think now i will mount a little switch under the steering wheel column with a relay to the battery. previously i thought of wiring it with a relay to the battery to the city lights in the eruoswitch or the window defroster or the FUNK switch (as the golf, being an auto tranny, has no ESP button).

here's a few pics of the install in the golf; the larger images can be viewed in my photo section. been almost about a week now and no signs of any leakage.

edit: i used 1/4" bolts, and the reason for the one large washer and then the thick smaller washer is because the holes for the head mount are too large for 1/4" bolts, so you need the larger washers to get a firm fit and not bend the washers at the same time. and there isn't really enough metal in that mounting spot to use any bolts larger than 1/4" IMO.

filing and holes for the fm100 head mount:



the combination of bolts, washers, nuts i used (stainless steel except the 2 thick washers are zinc plated):



the whole setup:

and another pic of the head:

VERY nice setup! How often will you change your filter?

Are you not worried about the filter plugging in the winter ?? I only ask because there does not seem to be any provision for warmed fuel to be returned to the filter ( like the thermostatic tee did on the OEM filter ). On my setup, I managed to plumb in a tee into the suction side of the filter so some fuel would return to the filter, but most would go back to the tank.

if the fuel has already gelled, the T-valve isn't going to help. the fm100 has a side-load heater option to heat the fuel in the filter when it's cold out. as far as i know, the Mk5's did away with the T-valve altogether...

I wasn't worried about gelling, I was worried about clogging due to fuel clouding. Maybe I am just worried for nothing, but at the temps either of us could experience, I thought it prudent to circulate some warmed fuel back through the filter.

I just realised that you are using a 5u filter, I am using a 2u. Might be an issue for me and not you. Electric heater might be nice though. Would remove all doubt if you ever thought there was a gelling issue. Just turn it on and wait. Might avoid a trip to a heated garage ! Hmmmm, wonder if I can get a heater in mine ...

the 5u filter i think is the better, less restrictive option. the 5u filter filters out 92-93% of 2u particles according to stanadynes papers... what size filter are you using? i'm using the larger 6". SUNRG did some tests as well as HermTDI and they felt the 2u filter was too restrictive... i personally have no data...

2u is more restrictive, but probably not too restrictive. the 6" 2u is probably less restrictive than the 4.3" 5u, but i concur, IMHO the 6" 5u is probably the best FM100 option for TDIs.

cheers!

Mine is a 2u Perma-Cool filter setup. I can't remember the size, but has to be near 6". The outer case of the filter seems to be near identical in size to the oil filter I use on my Mustang ( FL-1A, PH-8A etc ... )

Thanks for the info. I'll probably be doing me a FM-100 and a Mann Pre-Filter with in the next month or so. I'm not going to need to go with the heater since i'm down here in Houston, Tx. About how much room does the FM100 need? I'll be doing this in a 05.5 Jetta, so will try to take pics and post what i come up with for those that are thinking about it for the new design.

i do NOT recommend doing this on an A5. this is a replacement upgrade to an A4 filter which only filters to 58% @ 3-5 microns. the A5 features a new very upgraded filtration media that is over 95% efficient at 3-5 microns - and IMHO this excellent filter should not be replaced.

in your other thread you talked about adding a pre-filter / water-seperator before the OEM A5 filter and that seems reasonable in concept.

again, if it were my A5 i would NOT remove and replace the OEM fuel filter.

Is it possible to put a MK V filter on a MK IV? I already on an FM100 on my PD (MK IV) but would that be an easy upgrade for others?


I was thinking about trying to wire my heater up to my rear defrost switch.

it's possible, but IMHO the FM100 is an easier upgrade, less expensive and probably even a little better filter. but since the A5 OEM and the FM100 are so close in filtration efficiency, IMHO it doesn't make sense to go from A5 to FM100 or from FM100 to A5.

Exclamation 3/8" flared or MPT??

quick question about the hose barb and the port plug.

i was just down at the hardware store, and no surprise... they didn't have the 3/8" - 5/16" hose barb i was looking for. so i guess my small local Ace Hardware didn't come thru for me, i'll have to do to Home Depot or Lowes. the question is, while i was there i tried both a 3/8" flared piece, and a 3/8th" MPT (which i assume meant male pipe type) piece. the flared piece seemed to loose, even if i were to apply some tape. the MPT seemed too tight, after about 3 complete turns it became much more difficult to turn and when removed appeared to have scratched a couple flecks of paint away from the inside of the FM-100 thread.

which of these fittings do you recommend? will the 3/8" MPT fit with just an appropriate amount more force?

hopefully Lowes will have that 3/8" -> 5/16" barb piece, and the 3/8" plugs...
