Aeromotive 0 to 15 psi Fuel Pressure Gauge

Liquid Filled Gauges offer a better looking, more durable option for gauges that will live in a harsh environment like under the hood, attached to a high-performance engine. The problem with regular liquid-filled gauges is they can be temperature sensitive, with fuel pressure readings prone to rising and falling with the temperature of the oil in the gauge case, regardless of actual fuel pressure. As under-hood and therefore gauge temperatures can swing across a large range, this can be especially frustrating.
