Description

This in-tank fuel pump module is a high-pressure unit that flows 350 LPH and supports EFI engines up to 750 HP. It includes a pre-calibrated fuel-level sending unit for factory gauges and a HydraMat filter to prevent fuel starvation. Fuel pressure is internally regulated to 58 psi, eliminating the need for an external regulator or return line. Designed as a direct replacement for factory pick-up and sending units, it allows retention of the factory fuel tank and hard line.
