Does anyone know what part of the CP3 is leaking? I could never actually see were mine was actually coming from. And the dealership just said it was leaking, being replaced and wouldn't provide any specifics. I guess it really doesn't matter, but I always like to know. And count me in on the taking a month to get a replacement, not to mention a whole day and a half for them to decide it was leaking .

 

How many third gens have a leaking pump with the added filtration of a Fass, Glacier, Cat filter etc????? Does anyone think it is related to fuel quality/filtration?

what is the long term negatives with letting it leak till it drips...The new ULSD barely stinks compared to the original fuel....I don't smell it in my garage.

I'll surely put it on my list of dealer do's when I take it in if ever for anything else.

 

the fuel drips right onto your fan clutch wiring harness..sooner then later it will start to break down the wiring and the plastic plug connector.....plus it's a fuel leak!! on your brand new 45k truck
