Fuel line replacement

Stainless steel would be the way to go. You would have to fabricate your own fittings, but it is possible.

 

on European trucks they use plastic lines, like air lines. I'd say plastic line is better, more durable

 

Some Volvo's use plastic as well. I agree they are allot better!!

 

With all the bio blends out there I got nervous, I went to a local hose specialty shop and found they had some synthetic hose that supposedly is resistant to chemicals and the bio-diesel. I paid something like just under $400 for just hose and fittings, and then you will have a labor charge if you don't do it yourself.

 

Plastic is the best, fittings are easy to get hose is cheap and available, anywhere, it is very tough. I slide on sections of heater hose, to protect it where you are going to clamp or tie it.
I have seen units with Teflon hoses, great, But if you have a problem on the road where do you find a replacement?
Just a thought!

 

I may have messed up going the route I went, plastic is easy to work with like you said John, and definitely cheaper.

 

Synflex hose is really good. It's the plastic stuff, similar to plastic air lines.

We use it on all our replacements. It's great stuff, but it must be routed and secured good. It is not nearly as resistant to chaffing as braided hose. It also can be warmed up with a heat gun and formed to help hump it over or under frames and cross members (don't get it too hot though). The fittings are barbed fittings, the tubing just pushes on, no clamps or crimps. Once it's on, it's really on. You'll have to cut it or heat it to get it off, either way, you ruin the end of tubing getting it off.

The hose does fit DOT compression fittings too for an emergency roadside repair, just in case. We had a Pete once that had a big strap break off the frame that was holding all the hoses and wiring along the frame. It rubbed a hole in an air line an a fuel line. Road service was able to put in compression fittings to get him going and back to our shop for a new fuel line.
