Fuel pressure

[Gold 95]

Good afternoon I have a 95 1500 with a stock 305. What is the maximum fuel pressure that can be run on the stock injector? Current fuel pressure is 18 psi after replacing the fuel pump.

A. Your pressure gauge is inaccurate.
B. Someone has installed a high-pressure spring in the pressure regulator.
C. The fuel-return plumbing is restricted, or the new pump is extremely high-volume and overloading the fuel return.
