Quantum TBI to LSX Swap Fuel Pump 58PSI (LM7 LR4 LQ4 LQ9 L33) EP381 Direct Fit 82-95 GM, Replaces WIX 33737

SKU: QFS-F201

Using the C5 Corvette regulator/ filter is the tried and true method of providing all LS-based motors with the 58psi base pressure they require. Usually mounted close to the tank, this regulator has a fixed (non-adjustable) fuel pressure of 58psi and also provides inline filtration between the fuel pump and the injector rail. Both the feed (from the tank) and the return will connect to one side, and the single outlet will go to the injector rail on the motor. Includes mounting bracket and grounding strap as shown.
