The Precision Raceworks G-Series High Performance Primary fuel pump (Kits) are designed for customers looking to run all blends of E85. These pumps are ideal for customers looking to run a single fuel line to the front of the car and feed the high-pressure fuel pump and port injection from a single pump assembly.  (For B58 cars click here)

Caution!

Many other companies selling pumps are not protecting your high-pressure fuel pump or direct injectors with their fuel pump options.  When comparing other brand pumps to Precision Raceworks ensure there is a fuel filter in the system after all electric pumps either in the tank or in the fuel line. Companies using a Y fitting to join the factory pump (after the factory filter) and an additional pump before going to the top hat and not including an inline fuel filter are cutting corners and will cause premature failure to the high-pressure fuel pump and direct injectors.
