Best way to run return line for Fuel Injected engine.

[Pete68]

Hi, switching to fuel injected LS engine, whats the best way to run the return line? Has anyone used a stock fuel line and added it next to the existing line? Thats what Im thinking right now.

I have heard flexible braided lines leak fumes so I dont want to go that route. Any ideas?

Thanks

yes you can just make a second fuel line right next to the original one, the 69 camaro had both lines (primary and return) on the cars from factory, you can order a 69 fuel line kit from those restoration houses, classic industries, firewheel, ricks first gen, heartbeat city any of them have pre-bent line kits

Yes, that's what I did on my '67 using the new pre-bent line for pressure and the original line for the return. You will need some way for the lines to flex between the frame and the engine. I used steel braided hose and have had no issues.

Thanks guys, did you use 3/8 line for both feed and return?
