 The key to this kit is the billet adapter fitting. It is CNC-machined for precision fit and leak-free performance and attaches directly to the schrader valve outlet on the factory GM fuel rail. The front side of the fitting accepts a standard 1/8" NPT fitting, which matches the outlet on the included carbon fiber-faced, liquid-filled 1.5" pressure gauge.
This kit is easy to install and is absolutely necessary for applications using an adjustable fuel pressure regulator. The kit also adds a high performance look to any engine compartment.
The kit includes (1) Marshall carbon fiber-faced liquid-filled pressure gauge and the billet rail adapter. Additional 45* and 90* adapter fittings are also available, please call for details. A pressure gauge with the engine-turned finish is also available.
Note 1: The kit is shown installed on a 2010 Camaro fuel rail. Most applications (including the Buick 3.8L Turbo) typically have the schrader valve at the front of the driver's side fuel rail, resulting in a forward-facing gauge that works well. The supercharged Cadillac CTS-V has a vertical schrader valve in the middle of the passenger side rail, and an additional 90* fitting may be desired for this application. Please call for details and availability.
