Need plastic fuel tubing

[krawlr]

Anybody know where to buy the black plastic tube in bulk that Ford uses for fuel lines to the tanks? I need to extend the rear tank lines and repair the return line at the engine. I've found fittings with no problem. Maybe somebody parting one out will sell them to me?

here's what I do for chassis stretch jobs. I take rubber feul hose of the appropriate dia, slip it over the cut part of the plastic line and put a clamp on it. simple. done. been doing it for years and haven't had any issues whatsoever.

OK, I used the special barbs and rubber fuel hose. Somewhere along the line I got the impression that the rubber fuel hose was bad on a diesel.
So nothing special about it huh?

There are some hoses that won't hold up with diesel. Just be sure whatever you use is diesel rated.

OK, I did some digging on this. From what I found SAE 30R7 is what to use and is even good for biofuels.(and that's what I used) SAE 30R6 is only good for gasoline.

Corrections and clarifications welcomed.

The plastic dot rated air brake tubing is ok for fuel use, gas or diesel. Did all the research several years ago to have less material on hand for our truck shop. Compression fittings are available or put the end in some very hot water and push it on a barb fitting when it cools it is there. I have used it on bosch gas CIS injection systems and they run at 85 psi.
Have fun. BTW the quality of parts store fuel hose seems to be going to heck. Get yours from a hydraulic shop, buy big rolls, share with friends :Sly
