Description

Easily monitor your fuel pressure with these plug-and-play kits—the FAST LSX fuel pressure gauges. Designed to fit most aftermarket billet fuel rail kits, especially the FAST LSX fuel rail kits, they conveniently install on the end of the fuel rail for an easy way to monitor fuel pressure, which is critical to achieving ultimate performance with your fuel injected engine. With their black gauge face, liquid-filled internals, and easy-to-see indicator needle, these gauges are easy to read and durable. Best of all, their high-quality, heat-resistant silver casing delivers an ultra-high-tech appearance that enhances any engine compartment. Included full instructions will get you up and running in no time. Best of all, you'll never have to guess as to the state of your current fuel pressure ever again!

Product Attributes - Notes: When reading fuel pressure, keep in mind that a fluid filled pressure gauge will change it's reading as the temperature of the gauge case changes (Under hood temperature). Because it's sealed to contain the liquid inside, a liquid filled gauge no longer compares line pressure to actual atmospheric pressure, reporting the difference. Instead, it compares line pressure to the pressure inside the gauge case. As the liquid in the case heats or cools, it expands and contracts, causing case pressure to change as much as 1 psi for every 30 degrees temperature change of the gauge. Includes -8 SAE to 1/8 in. NPT fitting.
