My truck has been starting very hard lately. Very long crank time before starting. Runs bad when it does start until its running awhile. I figured it had an air leak in the fuel system. I go to pump the lift pump, and drip drip drip. The lift pump primer bellows is leaking. Are any parts available for these pumps or do I need a new one? (high pressure piston pump)

 

It's most likely just an O-ring; it won't hurt anything to experiment with re-sealing it, seeing as how the only other option is a new one anyway.

 

If it's leaking out of the little rubber tube on the back of the AFC, then your O-ring on the small fuel pin is shot. You will need to pull the AFC to replace it. You can get a complete re-seal kit from Bosch under part # DGK-121, I believe.
