Checked the wiki and did a quick search, couldn't find the answer. I think the fuel lines are 5/8", anyone know how much hose I will need to change both the supply and return lines.
On my 1987 the diesel fuel line is 3/8" supply side and 1/4" on the return side. The lengths will depend on how the hoses are run.
John is right on the sizes. Took 8' of the 1/4 and 10' of 3/8. Plenty of extra. Original routing did not make sense, my runs are more direct, therfore some extra slack. But better to have too much than not enough.
Ken : Here is an idea. When I changed out my supply line I installed a fuel cutoff ball valve just before the Racor filter. It is easy to mount on the engine wall with easy access from inside the door under the head sink!
I spent the extra $$ to get the CG Spec. fuel line. I later found out that that spec. allows the line to be in a fire for something like 12 or 15 minutes before it melts! As compared to the Gates Rubber made Diesel fuel line that will fail in a fire in about 5 minutes!! Go figure!!
A few thoughts
Ball valve already in place. Makes changing the Racor a lot less messy.
