AUTO METER 8463 Ford Factory Match 2-1/16" Electric Fuel Pressure Gauge (0-100 PSI, 52.4mm) - Perfect for Ford Vehicle Engine Monitoring & Performance Tuning

This is an expensive set-up, but I didn't want the type of gage where fuel is pumped to my dashboard to measure the pressure. This uses a remote sensor that is wired to a steppermotor gage in the cab. It needs 12V power and ground as well as the wires going from the sensor to the gage, so expect to spend a little time if you want a nice clean installation. My 2.3L 4 cylinder Ford Ranger didn't have much room to directly thread the sensor directly in to the fuelrail port, so I had to use another fitting to make it a right angle. I was having an intermittent fuel pump problem, and this helped me diagnose that it wasn't the pump or the wiring, but the relay that controls the pump, an easy fix. Pretty much paid for itself, and it looks cool in my truck.
