Gary,
Sorry my mistake, Airtek is the manufacturer of electric fuel pumps so I assumed that you had an Airtek electric fuel pump. That being said, are you having a drivability problem with your car? Does it seem like it is starving for fuel under acceleration?
According to the
service manual, the fuel pump pressure specification is 4.0 to 5.0 psi at 900 rpm and you said that you only have 2.5psi, that would lead me to believe that you have a defective fuel pump.
Did you perform a fuel volume test on your new fuel pump? The volume specification is 1 pint in less than 45 seconds, at 900 rpm.
