Direct-Fit Replacement

The Quantum HFP-390-UR is an in-tank electric fuel pump with an integrated regulator designed as an OEM replacement for compatible vehicles. It suits owners and mechanics who need a direct-fit unit to restore factory fuel delivery without modification.

Simple Swap Installation

Installation follows the standard in-tank procedure: depressurise the system, remove the sending unit, swap the pump, and reinstall with a new seal. The main risk is damaging the float arm or sender during removal, which can cause inaccurate gauge readings.

System Pressure Limits

The built-in regulator maintains the pressure specification required by the original fuel system, so the pump cannot support higher-flow injectors or forced-induction upgrades. Buyers needing increased fuel volume for performance builds should select a higher-capacity unit instead.
