High Pressure Fuel Pumps

In a direct-injection system, injectors receive fuel through a high-pressure rail. The high pressure fuel pump must match that system's pressure-control arrangement and engine application.

Choosing A High Pressure Fuel Pump Replacement

A-Premium offers individual pumps and selected paired packages for specific applications. Engine version, drive interface, fuel-line connections and electrical connector all affect the correct part.

High Pressure Fuel System Service

Fuel can remain under high pressure after the engine is shut off. Follow the vehicle manufacturer's pressure-relief and fuel-system safety procedure before opening a connection; a generic pump or battery-disconnect sequence is not a substitute for that procedure.

Frequently Asked Questions (FAQ)

How is the high pressure pump different from the tank fuel pump?

The tank or supply pump moves fuel to the engine's supply circuit. In a direct-injection system, the high-pressure pump raises pressure for the fuel rail and injectors; the two stages have different jobs.

Are high pressure fuel pumps always electrically driven?

Some direct-injection pumps are driven mechanically by the engine camshaft while an electrically controlled valve regulates fuel delivery. GM describes that arrangement on a specific engine, so the drive design should be checked for the vehicle.

Can a low-pressure supply problem cause a high-pressure fault?

A restricted filter, supply-pump fault or wiring issue can reduce fuel reaching the high-pressure pump. Delphi identifies these as possible low-pressure feed problems in a specific diesel system; test the vehicle's supply circuit before replacing the high-pressure unit.

Does a two-pump package mean every engine needs two pumps?

A paired package fits particular engine configurations. One listed BMW V8 set specifies driver- and passenger-side pumps; other listings contain one pump.

Are seals included with every high pressure fuel pump?

Package contents vary. The listed BMW two-pump set specifies that a gasket or seal is not included, so obtain the required sealing parts according to the vehicle's procedure.
