GlowShift’s Chevrolet GM LS Engine Fuel Rail Thread Adapter simplifies the installation process by adding onto the Schrader Valve of your engine's fuel rail, allowing you to install a fuel pressure sensor with ease. This LS Fuel Rail Adapter includes a 1/8" NPT Female to Male 90 Degrees Elbow and a -4 AN Fuel Rail Adapter fitting that can be installed to any Chevy LS1, LS2, LS3, LS6, LS7, LS9 and LSA engines. Every modern GM V8 fuel injection car has a Schrader Valve installed to check fuel pressure. Simply unscrew the Schrader Valve with a Schrader Valve tool, mount the adapter, and then mount the gauge to the adapter by connecting your fuel pressure gauge to the 1/8" NPT female port. The flexibility this fuel rail thread adapter gives you is vital because your ability to install onto the LS Engine’s existing GM fuel rail adapter Schrader Valve not only simplifies the process, but also eliminates the need to make any major modifications to your vehicle. GlowShift also includes unlimited tech support and a one-year limited warranty with each purchase.
