These fuel pressure gauges are designed to pair perfectly with both ACUiTY's fuel rails, as well as most other aftermarket fuel rails with 1/8 NPT gauge ports. To guarantee a quality product, ACUiTY has industry leader, Marshall Instruments, produce these gauges to ACUiTY's specifications. These fuel pressure gauges feature rugged construction and are liquid filled for vibration dampening. This model features a 1/8 NPT thread (compatible with our K-Series Fuel rails and many automotive fuel system applications). The gauge features a black bezel, red pointer, and satin black, powder-coated, steel case. The max bezel diameter is 1.75" and is the perfect size to pair with an ACUiTY fuel rail. These gauges are safe for use with gasoline and ethanol, so they will work in a variety of applications. If your fuel rail features -8 ORB ports but no 1/8 NPT ports, consider using ACUiTY's 1913-F05 adapter to allow placement of this gauge on a -8 ORB port on your rail.
