Not good?!?!
 

I took off the cover of my injection pump and there was diesel sittin on top of my afc wheel. I've never seen this b4 so I caould really use yalls help. I just hope my pump aint shot or something. The 4 screws weren't very tight at all on the cover... just need to know eats goon on with tha ol goat. Thanks for all yalls help. [dummy]

It's a leaky fuel pin seal. There's a link in the sticky that tells how to fix it.

Will I have to take the pump completely off?

have a picture of your custom fuel pin? if its too deep the small pin will go past its seal.

Nope just the top, or AFC. The body stays attached to the truck. You can replace the seals pretty easily.
