What are the fuel pressures readings? If no obvious reason on the surfaces are detectable, like a crack or porous casting on the housing, then possibly excessive pressure could be building in the system, like from aeration due to combustion gasses entering the fuel supply system through a bad injector seal. Heres some info that may or may not be helpful.

ok got the new oil fuel filter housing put on today and started up truck and it is still leaking out of the same place. On the old one i could see where it was leaking when i took it apart look like a little dent dont know how that happened other than the fuel leaking through it caused it. guess i need to check out my fuel pressure truck has just had 8 new injectors put in it hop it is not that. any ideas what would cause this
