Fits GM LS engine factory fuel rails.

The Vibrant Performance 16791 Fuel Pressure Adapter is designed to simplify the installation of an aftermarket fuel pressure gauge or sensor onto your Chevy LS factory fuel rail. By adapting the existing service port to a standard thread, this fitting allows for precise fuel system monitoring without the need for custom rail fabrication.

This adapter features a -4 AN female thread on one end and a 1/8" NPT female thread on the opposite end. For proper installation, the factory Schrader valve must be removed from the fuel rail. While optimized for LS applications, the -4 AN to 1/8" NPT configuration is also suitable for a variety of other plumbing and fluid transfer needs.

  • Thread Size A: -4 AN Female
  • Thread Size B: 1/8" NPT Female
  • Application: Factory fuel rail Schrader valve port
