I noticed smell of diesel while driving the truck and looked and saw small drips from under cp3 pump. Anything I can do to repair diy? Or am I better off getting a reman. Difficult to take off any special tools? Thank you

 

What year truck?

 

Its a 04 with 82k.

 

Typical CP-3 leak. You can reseal it with slightly larger and better o-rings if thats where the leak is.

 

Mine had the same slight leak for many miles now especially since I replace the lift pump. I wouldn't be worried unless it is spewing.

 

Its not leaking alot but enough to have a strong odor of diesel while driving.
