I have developed a fuel leak under the truck. Cant really detact anything at idle.
I degreased everything and sprayed it off at the carwash. Drove it for a while and when I came back home the underside was covered in Diesel fuel.

Any suggestions on what might be the culprit? I have a newly installed FASS. The fuel leakage was going on before the installaton so I dont think the FASS would be the problem.

Any ideas?

might check the return line coming off the vp44 that runs to the rear of the block. it connects to a 't' and mine was leaking from there; not as much as yours but it progressively got worse. it only seals with a neoprene type grommet that seals under the nut under pressure as the nut tightens down. the line on mine was slightly oval shaped as well as the grommet was nearly disintegrated.

The same line leaked on mine right behind the fuel filter.
