Nylon fuel line size

[captsb890]

I don't have an illustrated parts book--or CD--(haven't seen one but be nice to have)-but what is the size of the Nylon fuel line that is behind the rail pump going to the rear? and what size Dorman fitting would I need-----the plastic quick disconnect on my rail pump is broken----- I need to do a line there or replace that quick disconnect----Thanks---Sam

Pretty sure all the return lines were 5/16" and supply was 3/8"

Most parts stores in there "help" section has repair lines or kits. You find the right fitting, or fitting and short section of hose. It comes with a splice.

You cut the old line off, stick the end in hot water for a minute or two and that makes it soft enough to slide the splice in. After it cools, it shrinks and seals.

takes a little practice, hard to get correct the first time.
