I'm about to install my new set of Delphi injectors and started thinking about the fuel lines on the car. They're original to the 85 sooooooo probably could stand to be replaced due to the rubber sections on them, rubber being only good for so many decades after all. It will need to be done eventually, and might make sense to do before potentially crapping up the brand new injectors.
I know these are easily available from a number of vendors right now, but to my knowledge they all have the crimped rubber hose section, which is the main part I want to replace anyways. Given the hassle of getting new lines in has anyone found a better way to do these lines? I know some people have gone with braided tubing in the front, but that doesn't help the rears. I've also heard some not great stuff about the braided fuel line, but I'm not sure how much of that is old knowledge before they started using the PTFE.
Anyone know of a convenient source for stainless line that has some kind of fitting on it so that I can replace the rubber sections without dropping the entire line every X number of years? How have other people been solving for this?
Haven't considered that. The nylon looks so flimsy but it does just need to be the flexible union on the hard lines. Probably would need to do something different in the rear, though.
I can definitely see doing something like this. I'd want the PTFE sections to be short enough to be changed out without dropping the bumper but it looks like a good solution
Yeah, I've used nylon for repair for a few years now. Advance Auto carries S.U.R.&R. products, they make all kinds of fuel line repair parts. Sometimes I'll do away with the bolt on fuel filters and instead use quick connect type fuel filter. I made a setup to press quick connects onto nylon lines, use use a caulk gun and wooden clamps to hold the line.

Out of curiosity, why are you planning on replacing the PTFE sections? I'd get why if you were running CPE AN line, but PTFE lines are set and forget.

In general I'd like access to any line I'm using, rather than bury it under something hard to remove. I'm still learning about the PTFE line. I'm not sure how much of the "They leak after one year!" is old info or just parts that were done wrong as well
Been so long since I've used them, but I can't believe I forgot about Swagelok fittings. I'm betting that will be the perfect mix of ease of use and rock solid function.
My 88 project was frame up, all custom lines for everything.
I just gave my .02 in another forum last week about fuel lines.
My entire car (feed and return) are 3/8 aluminum fuel line with 37 degree (AN) flares and Parker push lok fittings. Works perfect and its easy to do. The aluminum line you can bend with your hands and never kink it - its that nice. All fairly cheap $ wise as well.
I just ran new brake lines using Nicopp metal lines. Can that be used for fuel line, of the right size, as well? It was easy to work with and supposed to be DOT approved for brake fluid. Anyone know?
Be sure to get all the parts - for reasons I can't explain there is one part # that gets you both parts of the supply line but two part # for the return line (at least in stainless).
Will be installing these soon. Looks like a lot of work (rear end out already replacing all the bushings) and the rear bumper cover has to come off.
