Product Description

Bypass plug with integrated port for fuel pressure monitoring or sensors

This bypass plug is designed to replace the factory fuel pressure regulator on LS1 intake manifold rails when using an external fuel pressure regulator.

  • Direct replacement for factory LS1 fuel rail regulator (1997–2006 5.7L LS1 engines)
  • Required when using an aftermarket external fuel pressure regulator
  • Integrated 1/8" NPT port for installing a fuel pressure gauge or sensor
