Fuel line typ and size?

The fuel line on my truck has Number 8 fittings for the supply line and Number 10 for the return lines. They have the crimped ends on the line.
I would think as long as the line can handle the pressure and volume of fuel they should work. Just need to get proper fittings to adapt.
Good luck.

 

Nope and nope. The larger fuel is not under pressure but is a suction line. A regular fuel hose would collapse.

 

whenever i have needed replacement fuel lines on a big truck i just had some replacements made up with hydraulic hose

 

That hose is great for everything. Air, fuel, coolant. Seems to be highly resistant to abrasion also.

 

3/4 is a pretty darn large hose i would not think original is any bigger than 1/2 or maybe 5/8, normally what i do is i take the hose off and run it down to napa or another hydraulic place i use and just have them make a hose that matches the old one, same length size and end fittings.

most original hoses iv come across have been originally whats called "truck hose" or "transport hose". with the screw on taper style fittings, you can buy everything you need to make new hoses with that as well and make them yourself. i like the hydraulic hose because its a much tougher hoses. and i like the crimp fittings better than the screw on style.

you could also use an hose. if you felt so inclined but i would guess cost would be more than hydraulic.
