1998 Chevrolet 3500 Pickup Q&A
1998 Chevrolet 3500 Pickup Question: Has anyone encountered a strange fuel leak with the 6.5 diesel?
Fuel is leaking heavily from somewhere above the starter (onto the starter) and also drains steadily from weep hole in bottom of bell housing (both only when running). Injector lines are tight and dry at pump and block. Watched from top and bottom of truck. Mechanic ran a scope to the injector pump. Checked pump, connections, and "valley" that pump sits in. Cannot find source of leak. Any info would be greatly appreciated. - twalls
sounds like you need another set of eyes. it sounds like a return line from the injectors may be leaking. it is those real small hoses that connect them all together. Roy - mastertech6371
I had a similar problem. One of the fuel out lines from the separator had broken, but the truck wouldn't run but a few seconds. The line is pressed into the separator. A new one is somewhere from $800 to $3000 dollars. - 02supercharged
