Fass Titanium leaking

14scorpion · Sep 13, 2015

Seems to look like my fass pump is leaking around the black solid blocks where the pump and filters come together. Hard to explain, every time I stop I have a small spot of diesel bout the size of a quarter on the ground, dries up and is gone by morning so it's not leaking while just sitting. It only seems to leak after I drive and then park. All fittings are sealed and tight and filters are both right with seals in tact. Any ideas?

It's most likely leaking from the weep hole on the bottom of the pump. I took all the seals to a local hydraulic supply store (Martin fluid power) and they were able to match everything up.

Mine was out of warranty though and I was just going to scrap the pump if my rebuild didn't work.

It is the coming from the hole on pump and just rolling down the mounting bracket. I just figured it wasn't supposed to leak out every time you shut the truck off.
