Fuel Pump: Specifications

Measure the fuel pressure while disconnecting pressure regulator vacuum hose from intake manifold.
Fuel pressure:
Standard 284 - 314 kPa (2.9 - 3.2 kg/cm2, 41-46 psi)
After connecting the pressure regulator vacuum hose, measure the fuel pressure.
Fuel pressure:
Standard 206 - 235 kPa (2.1 - 2.4 kg/cm2, 30 - 34 psi)

NOTE: The fuel pressure gauge registers 10 to 20 kPa (0.1 to 0.2 kg/cm2, 1 to 3 psi) higher than standard values during high-altitude operations.
