I have a stock 95 mustang GT it's running like crap, it surges while your driving, has slow throttle response and if you floor it it will almost die then slowly pick up. I did a fuel pressure test, with key turned to on position the guage barley moved! Start the engine the gauge slowly moves to 34-35, pull the vacuum line and it's 44-45. So I replaced the fuel pump and filter and it didn't change a thing!! I checked the fuel lines for any kinks and such but did not see anything. Any ideas?

Yeah all im getting is 186, 172, 176 and 182 but I can't find anything on 182? So I don't know.
Bingo!!! That was it. Thanks. One more question, why does the fuel pressure barely register with the key in the on position? I was told it should jump up to 35-40 instantly?

it should take like 2 seconds for it to reach 35 psi. Did you install the filter the right way?
I have a 255 pump and I idle at 30psi.

I believe so from the tank to the side marked "IN" thats the way the old one came off, but the old one did the same thing though.
