Paul H. from Oklahoma
Piper PA-28-151 Cherokee Warrior

Installing [EI’s FP-5L] in my RV 6. . . owned an FP-5L 6 years ago in a Cessna 206 on floats in a commercial operation in Alaska. Getting every ounce of payload, and coming home across Cook Inlet with the Cessna gas gauges near or on empty, I spent a lot of time explaining the benefits of the Fuel flow gauge… and reassured my passengers there were 12 gallons of fuel on board. I’m a believer…

Terry R. from Washington
Van’s RV-6

A clear capable replacement for a cluster gauge. Vivid colors used which make it easy to see engine status at a glance.
