K-Tuned Fuel Pressure Gauges are filled with liquid to prevent failure caused by engine vibration and constant movement. This liquid-filled (shockproof) design keeps the needle steady when the engine is running. Unlike cheaper and less accurate gauges whose needles bounce around and are hard to read, our high - quality gauge accurately measures pressure from 0 - 100 psi. It features an all - black finish with yellow lettering and numbers, a red needle, and the K - Tuned logo on the bezel. Applications include all K - Series engines and are also universal. Also, check out our 1/8 NPT 90 deg and 45 deg fittings to adjust the gauge angle for better visibility.

Using your K - Tuned Fuel Pressure Gauge is easy. First, install it in your engine system. Make sure to use our recommended 1/8 NPT 90 deg or 45 deg fittings if you need to adjust the angle for better visibility. While the engine is running, you can easily read the pressure on the gauge as the liquid - filled design keeps the needle steady. As for maintenance, keep the gauge clean. Avoid exposing it to extreme temperatures or harsh chemicals. If you notice any issues like the needle not moving properly, check for any loose connections or signs of damage. And always refer to the engine's manual for the correct pressure range for your specific engine.
