About a month ago my fuel system started acting up. The harder i acclerated teh more the fuel pressure would drop. I had to EASILY push the gas pedal to go anywhere to keep the fuel pressure at 40psi. So last night i went ahead and replaced the fuel pump thinking that would be it. Wrong, the problem is now worse. I cant even drive my car. If i tap the gas pedal the fuel pressure quickly takes a dive towards 0 psi. i dont know what is wrong. I changed the fuel filter and all. This is even with my 255 in line pump...

I assume you're running an FMU? Did you hook it up right? No vacuum leaks?

Check your fuel pressure regulator,(Make sure the vacuum hose is on and functional)
