I have a leaky line near the fuel tank. Can the original steel line be replaced with rubber?

And can I get away with only replacing that short section? (running from the pump to the tank?

thx!

 

make sure you use fuel injection hose, and not plain gas line. do not use those worm gear common hose clamps, use proper FI clamps that look like...



as far as how much to replace, kinda depends on why its leaking. me, if the car was a keeper, I'd be considering using brake line tubing and fabricating new metal lines.

 

Noted. The current line is rotted (from road salt i would assume) near the fuel tank.
I'm thinking the 740 will be a keeper…she'll need some work though, that's for sure

 

You could use the copper-nickel tubing (cunifer) thats used for brake lines as a fuel line. its stainless, doesn't corrode, its quite ductile, and very durable and pressure safe. it doesn't fatigue and crack under vibration like copper or brass tubing would. Volvo has used this for their brake lines since 1976.

stuff like this,
5/16"/8mm Fuel/Hydraulic Line

 

hi Pierce,

if there's a pin-hole sized leak on a metal line, do you think the suggested clamp could cover and seal it ?

thanks!

 

jbweld if you have to for short term. Other wise no, clamp wont work`

 

gas tank jbweld did the trick on the fuel line... thanks!

 

carry a large fire extinguisher rated for gasoline fires at all times.

as an FYI . Glad the jbweld worked. I wouldnt trust it on a long term basis

 

no! and I will carry the fire extinguisher!

thanks!
