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…
OLC-2 Connector
The OLC-2 eliminates the need for soldering, crimps, and expensive connectors, all while creating a perfect connection between two wires. The two wires are stripped 5/16″ and then slid into opposing ends of the OLC-2. A set screw on each side of the OLC-2 is gently tightened. The OLC-2 can also be used to create perfect connections with Thermocouple wire, which means no more bulky TC connections.

The tach looks and operates amazing. Extremely accurate.
Much better quality with the bezel and buttons and knobs [vs. competition]. Also much easier to navigate and add fuel.

We chose your product because of the great support and reputation your company sustains.
The older EI ultimate engine analyzer that came with my plane that I bought 7 years ago has always worked flawlessly.
Very happy with our new tachometer!
I really appreciate the quality of communication about my order. The instrument offers the right functionality (being a primary instrument) in the right form factor for my application.
Works Great!

I won a FP-[5]L and had it installed in my c150. I was/am impressed with the accuracy and ease of operation of the FP. I wanted a new tach and I trust (and verified) that the EI R-1… would be my best choice. I am not a rich man. These instruments are affordable and incredibly accurate. Already planning my next buy from EI.
