GlowShift’s Tinted 7 Color Series 100 PSI Fuel Pressure Gauge ensures your fuel pressure is running at optimal levels, and is not too low which could result in loss of horsepower or damage to your fuel pump or injectors. This 100 PSI fuel pressure gauge has been updated to include a 1/8-27 NPT electronic 100 PSI fuel pressure sensor allowing it to be installed directly to your fuel system with the included 9' sensor harness. This new sensor is twice as small as the previous model and offers extremely accurate readings directly from the source. This gauge features an illuminated red needle that will sweep 270 degrees and is powered by stepper motor technology for smooth needle movement and extremely accurate readings. Featuring a low profile magnified tinted lens and 7 color through dial LED lighting this gauge lets you match your factory dash lights or add a custom look to your interior. Our 7 color through dial LED lighting system allows the user to easily cycle through 7 solid color modes, along with 2 color cycle modes, and for easier night driving the LEDs can be dimmed 30% when connected to your factory headlight switch. With the included color memory recall feature you don’t need to worry about adjusting the color of your gauge every time you turn your vehicle.
