Fuel Line Sourcing Issues

[DrivesLikeFoust]

Hello there. I have an 81 Fiat 2000 FI Spider and I am currently rebuilding the engine. My metal fuel lines are rusted and causing leaks. I have checked around for suppliers of this line and cannot find it. Can you get it pre-bent or at least on a roll? No one seems to have the right size. I have also heard that people have just run rubber fuel hose in its place, and am curious if this could be a last resort option. Thanks.

I change both and I think it was 5/16 25'roll at Auto Advance

I'm with Orford. I would not be comfortable with rubber fuel line running through the passenger compartment. I purchased a 25' roll of steel brake line for about $10. That was enough to do both lines even after kinking one and having to re do it. I used a cheap brake line bender and pre bent them on the floor before installing them. I put a flare on each end to aid in clamping.

I got long straight sections of stainless from a welding supply many years ago. PITA to deal with but was thin wall unlike the aluminum and will not have any issues ever. Worth the effort in my opinion.

Rather than normal brakeline, rubber fuel hose or braided line, consider Cunifer brake line.

Cunifer is a copper nickel alloy used for brake line on higher end cars and will not rust and is easy to work with. It is perfect for fuel systems. I would use a 5/16” line for the supply and 1/4” for the return.

It is easy to work and is now available at most auto parts stores such as Advance Auto etc.

Ah okay! Funnily enough I believe I have some Cunifer line left over from the brakes. Thanks for the tips.
