Fuel Pump

NOTE: Fuel pump performance measures fuel pressure, not regulated fuel pressure.
4-CYLINDER FUEL PUMP PERFORMANCE

Application (1) Pressure psi (kg/cm2 )
Camry 44-50 (3.1-3.5)
Celica 38-44 (2.7-3.1)
Corolla & RAV4 44-50 (3.1-3.5)
Tacoma 38-44 (2.7-3.1)
Tercel 44-50 (3.1-3.5)
T100 & 4Runner 38-44 (2.7-3.1)
(1) Check fuel pressure with engine off and using scan tool connected to data link connector No. 3 with ignition on to activate fuel pump or by connecting battery voltage to terminals on electric fuel pump.

Application (1) Pressure psi (kg/cm2 )
Supra
Non-Turbo 44-50 (3.1-3.5)
Turbo 33-40 (2.3-2.8)
(1) Check fuel pressure with engine off and using scan tool connected to data link connector No. 3 with ignition on to activate fuel pump or by connecting battery voltage to terminals on electric fuel pump.
V6 FUEL PUMP PERFORMANCE

Application (1) Pressure psi (kg/cm2 )
Avalon, Camry & Sienna 44-50 (3.1-3.5)
Tacoma, T100 & 4Runner 38-44 (2.7-3.1)
(1) Check fuel pressure with engine off and using scan tool connected to data link connector No. 3 with ignition on to activate fuel pump or by connecting battery voltage to terminals on electric fuel pump.
V8 FUEL PUMP PERFORMANCE

Application (1) Pressure psi (kg/cm2 )
Land Cruiser & LX470 38-44 (2.7-3.1)
(1) Check fuel pressure with engine off and using scan tool connected to data link connector No. 3 with ignition on to activate fuel pump or by connecting battery voltage to terminals on electric fuel pump.
4-CYLINDER REGULATED FUEL PRESSURE

Application Tested At Idle W/Vacuum psi (kg/cm2 ) At Idle W/O Vacuum psi (kg/cm2 )
Camry (1) (1)
Celica 33-38 (2.3-2.7) 38-44 (2.7-3.1)
