The AMS Performance Red Alpha Stage 1 high pressure fuel pump is a direct-injection HPFP upgrade that flows over 338 LPH with a maximum operating pressure of 180 bar. Its CFD-optimized design uses all stainless steel, laser-welded construction that seals the pump against leaks and is fully E85 and flex fuel compatible. AMS rates it for stock turbo builds up to 500 WHP on E85, including the ALPHA 5 and RA500 packages. Every pump is flow tested and inspected, and it ships fully assembled with its mounting flange, electric harness adapter, OEM-type low and high pressure fittings and install hardware.
