Pressure Regulator Test
NOTE: Low fuel pressure can be caused by inadequate fuel supply, a defective electric
fuel pump or fuel pressure regulator. Verify adequate fuel is being supplied to the vapor
separator. If fuel supply is proper, inspect final filter inside outlet fuel fitting on vapor sepa-
rator for debris. If filter is clean, perform amperage draw test on electric fuel pump. If am-
perage draw is within specifications, replace fuel pressure regulator.
Purpose: This test will determine if a weak, plugged or open pressure regulator is causing inadequate fuel
pressure in the system.
1. Connect pressure gauge 91-881834A1 to EFI test port.

2. Turn ignition key switch to “ON” position and check fuel pressure reading on gauge.
If pressure reading is below 41 psi (283 kPa) replace regulator.
