I HATE LEAKS!!!
I have noticed since it has been very, very cold that I have developed a small but noticable diesel leak dripping down under the CP3. It ends up dripping off the small wire harness underneath the CP3 which I think is the Cam Positioning Sensor wire? Any ideas why or where it's leaking from on the CP3? This sucks because I just installed a FASS with higher pressures than the stock 9 psi. I'm guessing it's from the very cold weather, not the 17psi from the FASS...Thanks for any help or tips. I am in the process of sending my extra 08' CP3 to John to be modified but am still curious WHY??

 

This malady has been happening since 03 when the cp3 pump appeared.Its under warranty and needs to be replaced if its coming from between the cp3 halves.If you want do a SEARCH CP3 leaks in cold weather.Lots of posts on it.I'm surprised its still occurring in 07 model year.Just in case you or the dealer tech might want to inspect it close.It could be a external fitting needs a snug up.

 

I haven't touched anything and it's not leaking from the FASS fitting?? They will probably blame it on my FASS???

 

mine was leaking between the plunger housing and the front part of the pump so i took the pump off and did some research and found the orings and seals to fix i took the pump apart and put new seals and orings in it over 2 years ago and has not leaked since. it was pretty cool to see the insides of the cp3 i also modded it at that point since i was in there

i didnt read your whole post mine was leaking in the same spot yours is the i put a tst on my truck and that is when i found mine leaking becuase that cam sensor was full of diesel fuel when i unplugged it.
