FiTech Fuel Injection 80117 0-100 PSI Oil-Filled Fuel Pressure Gauge
Accurate fuel pressure monitoring is vital for diagnosing issues, tuning, and ensuring your high-performance electronic fuel injection (EFI) system runs safely and efficiently. The FiTech 80117 0-100 PSI Oil-Filled Fuel Pressure Gauge provides a crystal-clear, vibration-dampened reading designed specifically to withstand the harsh environment of a performance engine bay.
Featuring a compact 1-1/2-inch diameter gauge body, this liquid-filled unit dampens needle bounce caused by engine vibration and pressure pulses, giving you steady, reliable readouts. It is equipped with a convenient 1/8″-NPT male fitting on the back, allowing it to thread directly into a matching female port on fuel regulators, rails, or distribution blocks.
