Will any fuel hose work?

pedroYUL · Feb 2, 2013

I have a leak in the hose that connects the metal fuel line (after the filter) to the tandem. It is a short Z shaped hose but to change it with original parts I would have to buy [FONT=&quot]038130308M to the tune of $250 before taxes.

Would just any fuel hose from Canadian Tire work?

The leak is bad enough to leave 30-40 cm patches overnight.

Do you really think $65 per inch is expensive?

The angles and close spacing of the tube and pump inlet may make it difficult to route the hose without kinking. You may have to make a loop to get the approach right, but otherwise just use any fuel line. I have been using the local parts store kind of fuel line for diesel without problems.

Yea a loop is what I thought and exactly what I did. I paid about 6 bucks (tax in) for a foot of 7.9mm fuel hose at CT.

This is the right hose for next time:

BTW, the leak at the hose is solved but the real leak was at the tandem. Time to change it out, as that was already fixed with a sheet of Viton but the viton was having issues with the winter. Leaking a river when cold.
Old gasket in and it leaks a drop every couple of seconds at idle.

I've got a (very minor) leak in the same small Z shaped section - mainly because whoever owned the car before me had this section of hose replaced, and used regular fuel hose.

I would REALLY like to get my hands on the original hard formed section, but without blowing $200 on the whole apparatus it connects to....

Anyone have any luck?

And how well does the loop method with the generic hose work? I might go that route if I can't find the hard Z.

Are you sure it's the pump leaking? I relaced mine due to a leak and I believe all that was leaking was the $10 mounting gasket. Now if the top cover is leaking, time for a new tandem pump.

The real deal is $144 at 1stvwparts.com.

038130308M

It includes the fuel temperature sensor, I believe, and the metal lines accross the front of the engine.

No doubt. It is in fact the outer lid. I am sure I could make it work but this is my daily driver and I have no choice but a change of pump. I already got one from Jimbote, a Bosch.

This LuK I have has a metal gasket for the outside lid. This metal is also embedded in a polymer but looks like it is not covering the whole metal now. I think if I brush some RTV back into the metal may work.

The loop works like a charm. Just make sure you use 1 foot and the right internal diameter. The hose I got was a tiny bit bigger diameter but it is working fine with worm type clamps.

You might want to look for some other sealant, RTV breaks down very quickly when exposed to fuel.

I also did the same thing with 5/16" ID hose -- Parker Superflex 39705. The OEM hose has an 8mm ID and 5/16" is very close (about 7.93mm). The OD of this new hose fits the existing clamps very well. It was about $5/ft at my local biodiesel coop.

1 foot was a little too tight of a loop and I worried about it kinking. I was also concerned about it rubbing against nearby metal hose clamps and cutting another hole. I ended up making a wider loop with approximately two feet that only ever touches the plastic air box and other hoses. It's been fine like this for 2-3k miles.

Here's a picture:

39705 is part number
B100 biodiesel compatible from Parker $1.40/ft

...just tapped out with a thumb or 2, please don't mind the abbreviations and grammatical faults.

For the record, 16" of 5/16" fuel hose in a loop worked nicely.
Haven't decided yet if I want to get the 038130308M assembly and do it "right," but if you're inclined that way the best prices (early 2019) seem to be at 1stVWParts.com ($150ish plus shipping) and IDparts.com ($164ish plus shipping).

I have used Tygon fuel hose. It is bio safe and clear. You can make the loop with about 9 inches without it closing off. Even better is you can see if there are any air bubbles

Will any fuel hose work?
