This kit allows the installer to tap into the Schrader valve outlet on the fuel rail and connect directly to a high-quality pressure gauge that can be mounted within the driver's field of view.
The kit includes a Marshall 1.5" liquid-filled fuel pressure gauge, an aluminum gauge adapter, a Teflon-lined 36" #4 AN line that is coated to prevent chafing on underhood components, and a gauge panel with hardware.
The gauge panel can be mounted underhood for convenient viewing when adjusting fuel pressure, or above the hood, facing the driver, so that pressure can be monitored while the vehicle is under load.
Note: This kit is not designed to be mounted in the passenger compartment. A fuel isolator or an electric fuel pressure gauge must be used for interior installations.
