Need to run both engine feed and return lines on my son's 37 sedan.  Installing an LT1 multi port injection engine and will be using an external high pressure fuel pump along the frame (like I did w/my 33).

Anyone have experience with the plastic stuff? I know it would be easier to run it from front to tank, then could use modern high pressure quick release fittings, not even sure if the lengths would be excessive for plastic.

Also wondering about cost steel vs plastic?

As you know GM uses plastic line on most of their current vehicles and I have not seen or heard of any problems or failures. It has a very high burst pressure rating and I have seen some trucks run lengths well over 10 feet. The only thing to watch out for is having close proximity to exhaust components.

Moose...haven't seen the line used in that length...but good to hear.  Been looking around for pricing for example a 25' coil to compare with steel pricing...haven't located a plastic fuel line source yet. I'll need 3/8" and 5/16".

 I dont like plastic fuel line on a vehicle. We use the blue plastic line on our sleds,quads,and bikes,but on a car,I wouldnt. Doesnt the plastic line that is oem use an O-ring fitting similar to a pex fitting? I guess when I hear plastic fuel line I think of what we use on the sleds.

Dorman Products offers it. I'm sure someone in you area carries their products and could get it.

The plastic I'm referring to is the black high pressure stuff used on all new vehicles.  Normally see it in short lengths feeding tank fuel pumps etc.

That's what I'm looking for...BTW they call it "nylon" fuel line.

Thanks

 That isnt what first came to my head! The only flexible line Ive ever used was the SS braid over teflon tube from aero quip or parker. Shows how out of date I am!

By searching for "nylon" fuel lines I have located the info and pricing.  Looks like good ole steel tubing is still cheaper to run. May still use nylon for short runs that could use flexibility.

Thanks

Ed,
Glad these guys were able to help you.  I'm still back in the 70's with carbs & steel fuel line.

If you work on any of the new cars and replace fuel lines etc...salvage the used barbed fittings/connectors, it's possible to re-cycle them.  Those fittings/connectors are the most expensive parts when using the nylon tubing.

You would think nylon fittings/connectors would be cheaper than brass fittings...doesn't appear to be the case.

 Maybe because they are made here instead of there?
