Archived HELP! Leaking fuel in Two places..

[jtadysak]

hey guys,



Noticed today that my truck is dripping diesel in two spots.



one leak is on the drivers side of the engine, you can see the part from the inner fender I think it is a gasket leak, but im not sure if it is the lift pump, or the fuel transfer pump, ideas?. . The other is coming from the breater hose underneath the truck (The piece of plastic tube coming down the engine) it is leaking diesel as well, usually it doesnt leak at all, or leaks a small bit, its also got a little bit of smoke coming out of it, my oil does NOT smell like diesel fuel... . What to do? Do I have these parts right? Ideas? Need help fast, I need to tow something across the state on thursday. Thank you. -Jordan

The blow by from the breather hose is normal.

Lift pump and transfer pump are the same thing.

So it is the Lift pump, primer button (o ring) hose between fuel pump and fuel heater, fuel heater ( don't recall if this one is visible).

Problems fixed with new larger cummins lift pump installed. Both leaks are gone. Old lift pump has a small crack in the bottom of it. -JOrdan
