QFS Fuel Pressure Regulator/Filter with -6AN & -8AN Fittings for 1999-2004 Corvette C5, LS-Swap Conversion, 58 PSI

This is the correct filter/regulator required for LS Swaps using returnless style fuel rails and also popular when doing popular the TBSS/NNBS Gen IV intake manifold swap. 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.
