As title states, looking for a complete set of the rubber lines from an early 944NA, from fuel tank all the way to the rail, every single piece of rubber fuel hose.

Let me know what you've got.

not sure where, mabey pelican..but i saw a post about making your own rubber fuel lines. its quoted a site with all adapters and tubing, to be used with a special but not to expensive crimp tool.

i want to remake my fuel lines but not the ones on my car, so i can minimize the downtime. thanks for the link

Are your current ones actively leaking? I suspect any used ones you find won't look much better. Also, the hookup at the fuel damper was changed somewhere in 84 so you need to make sure you get the correct stuff (the fuel damper on some have only one connection).

You can buy the rear hoses new (I think, you could ~4 years ago).

When I replaced the front lines on my 83, I cut the flares with a tube cutter and used a couple of good quality fuel injection hose clamps on each line. No issues. I had a shop size up the fitting on the supply line to the rail and they installed a new fitting on the supply hose.

BMW runs a hose clamp setup on the supply side of my E36, and they don't have frequent fire issues. I wouldn't be worried about it if you use appropriate hose and clamps.

they arent leaking, i just want someones used lines so i can rebuild them with new hose in order to run E85
i would like to either have the fittings recrimped with fresh rubber or do you think maybe i could use braided lines with the stock fittings? or should i go AN?that is cost prohibitive.

Mike C.

I see. They shouldn't be hard to find although I'm not sure if many people saved the long supply line from back to front. DC Automotive maybe.

I would say don't do braided lines without getting AN fittings - the braided lines won't really seal well with clamps. If you build the lines yourself though, I can't imagine that getting AN fittings and braided line/hard line would be too much more expensive than buying someone's used setup and then buying new rubber to rebuild those lines. In fact, if you replace the hard-lines as well, you can probably avoid having to use most of the expensive metric-AN adapters (hardline-AN adapters are pretty cheap in comparison). Check out anplumbing.com - they have pretty good prices on Earl's plumbing parts

i was quoted about $20 a hose rebuilt. i dont plan on doing the hard line, just the rubber stuff.

looks like i might be able to do something similar to the lindsey fuel line kit for the front end for not too much money. should be interesting.

Here is the fuel line diagram. Note where the hoses crimp onto the hard line where it comes up the firewall. IIRC, I did this in-situ with a small cut-off wheel.

i havent gotten down to measure them yet but lindsey says the late fuel hard lines are 8 and 10mm pipe. they use compression fittings for their kit. think that a 3/8 and 5/16 compression fitting would do?

Apparently the supply line-to-rail fitting is common enough. I don't believe it was AN. I have no idea what it actually is, though. The rail-return connection is a clamp from the factory, and the other ends were clamped.

To keep cost down, I used plain Goodyear hose that specifically said fuel injection rated (~200 psi burst).

Bavarian Autosport (national BMW retailer) sells metric injection hose from Germany (to help someone doing a search in the future). I don't think it has been tested for E85, though.

white924s

Sorry to say, but you really need the metric fitting to get a good seal (and with fuel lines, you don't want to really take chances). That's why I suggested replacing the hard lines - you can replace them with standard sized lines to use the cheaper 3/8 or 5/16 fittings. If you bend it yourself, stainless tubing isn't that expensive

white924s

That being said, for my car, I got the metric adapters. But if I were to do it again, I would get 3/8" tubing and replace the hard lines all the way back. Come to think of it, this might not be a bad spring project...

Page down about half way in this link and it shows how you can re-use the factory fittings with the crimped on shell (this example is for AC hoses but the technique is the same for fuel hoses too). I did this over 10 years ago with my fuel supply/return lines in the engine compartment using good quality hose clamps and have never had a problem.
