Re: New fuel pump, new regulator, still has fuel pressure issue..

It's a start.

Leak down with both lines clamped pretty much points to injectors. Especially if there is no sign of external leakage. Make sure to clean the injector holes in the intake with a bore brush of some sort, and use a small coating of engine oil or bearing grease on the o-rings when installing. (Dont use silicone based greases or sprays due to oxygen sensor damage.)
