Quantum EFI Liquid Filled Fuel Pressure Gauge 0-100psi 1/8 inch NPT 1.5 inch /38mm

To maintain the engine’s performance of any vehicle, it is important to install a fuel pressure gauge. A Fuel Pressure Gauge can be a great diagnostic tool for keeping an eye on your fuel system to ensure it is running at peak performance levels. Fuel Pressure Gauges monitor the fuel pressure in your engine to prevent damage to your fuel pump and injectors. They can also help diagnose an overall loss of horsepower. In a liquid-filled gauge, the fluid fill effectively dampens system pulsation, making the gauge pointer easier to read.
