Show original supplier description
This pump is tested for pressure and volume, ensuring reliable performance. It is compatible with both gasoline and E85 fuels, offering versatility for different setups. The pump is constructed from durable billet aluminum and is available in black or blue finishes. It features -08AN ORB female inlet and outlet ports, and a robust horsepower rating of 2000 HP. The unit operates at 106 GPH at 30 PSI and 72 GPH at 80 PSI, with a noted current draw of 14 amps at 45psi. The design does not include a bypass function, seals, or strainer, but it does come with a steel mounting bracket finished in zinc plating. Magnafuel tests every pump and regulator for pressure and volume, and all units are serialized and marked with the brand's logo and name to guarantee authenticity. It is important to note that the ProTuner series, including the MP-4303, is designed for vehicles not subject to emission controls and is a continuous run pump. Magnafuel prefers to troubleshoot directly, so customers experiencing issues should contact Performance Parts Racing or Magnafuel before initiating a return.
