Title: Replacing Fuel Hose??--------And Not Getting Ho$ed
Post by: AudiVWguy on April 08, 2009, 04:31:55 pm

I'm going to replace all the fuel hose on the caddy this weekend. I started calling around for pricing and was getting numbers as much as $5.25 a foot. This is for the German stuff with the woven outer cover.  I started calling around asking if there is any difference between gas and diesel and I kept getting the answer no.
So I'd like to use one of my life-lines..... I choose Ask The Audience  :D
Does anybody know of any long term problems?
What about the Viton type of line?
Thanks in advance,

What fuel hose are you changing exactly?

this is for the return lines on the injectors, yes?

I went to a local hobby/model store and picked up some fuel line for a nitro powered RC car, about $1 a foot and is 100% silicone, stands up to nitrometh so diesel should be no problem.

it comes in some cool colors too!

Sorry, it's all the larger hose. Inlet/outlet on the fuel tank. 2 pieces about 2 ft each. A piece from the hard line to the filter, into the pump and back to the hard line return. This stuff looks like it was never replaced from the factory, about 28 years ago.

just go into any auto parts supplier and tell them you want fuel line rated for diesel.

not cloth covered, but cheaper, has worked for me for a long time

It's important to get clear fuel line.
 You can use vinyl
 or go to a motorcyle shop and get urethane.

Which is longer lasting, vinyl or urethane? I can see these in the engine bay but underneath off the fuel tank. Wouldn't that be a more harsh environment?

i don't see any reason to replace the hard plastic fuel lines from the tank, unless it was somehow clogged up.

edit: or punctured  :lol:

Fatmobile, good call on the motorcycle urethane clear line. It's very heavy duty. I used it from the filter to the pump. Black fuel line from the tank to the hard line running to the front.
It's amazing how much better it starts and runs when there's no air in the line! Everyone should consider clear hose going into the pump.  8)
