A high pressure electric fuel pump is designed to be used within a multi-point system for electronic fuel injection as well as for fuel injected applications. Engine systems requiring high volume delivery of fuel require these pumps for optimal performance.
People assembling an engine system for circle track racing, drag racing or street racing, as well as any other application that requires large amounts of fuel delivery are the target market for a high pressure electric fuel pump. These are available both in-tank and inline, depending on the configuration of the system.
High pressure electric fuel pumps are available for systems using gasoline from the pump, diesel, alcohol, methanol and E85, and universal pumps are available as well. It is important to get a pump that is QS9000 certified in order to ensure product quality.
One high pressure electric fuel pump that has received multiple positive reviews is Walbro model GSL392BX, as of 2015. Reviewers indicate that the pump is easy to install and works quietly. One concern that some reviewers noted was that the pump does not come with any mounting hardware, so it is necessary to supply such items as the nuts that connect the wire terminals to the pump posts.
