    On your model there's no place to connect pressure gauge unless you have special tools for a toyota.
    (that I know of)
    I wouldn't hesitate to replace the FP on your vehicle because of it's age.

    Correct, kitch!

    There is no "service port" like you find on newer versions.
    You'll need to adapt the banjo fitting at the fuel filter or fuel rail to get an accurate fuel pressure tester reading.
    Fuel Pressure:
    At Idle: 33 - 37 PSI (226 - 265 kPa)
    At WOT: 38 - 44 PSI (265 - 304 kPa)
