Works Great! Getting used to menu the more I fly — Nice addition to airplane.

Dick S. From Oregon
Cessna U206F

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

Good engineering support.

Flying Academy from New York
Piper PA-28-161 Warrior

Easy to install and everything you need inside package. Good price, nice instrument and simple to use.

Pantelis K. from Greece
Piper Seneca I

The installation was straightforward and quite easy. Reliability and accuracy far exceed the original [aircraft’s] oil pressure/temperature systems. Also, the price was about a third of the cost to replace the gauge cluster.

Casey R. from Oklahoma
Cessna 172M

Excellent installation instructions [&] recommend[ed] by others.

Ben C. from Alaska
Piper PA-22-160

EI tech support is the best.

W. Bowman from Texas

Customer service always quick and easy. [I chose E.I. because of] price and being recommended by friends.
