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…
Awesome product. Fast easy installation.
I have worked with and installed a few of your competitors’ and your systems. EI instruments’ ease of use and installation make these systems my go-to choice and number one recommendation to customers.
I love my new EGT. Very accurate and has ambient air temperature so I know how cold my engine is before I start it. Easy to see lighting.
Pleasure supporting folks with like values.
EI’s products are the only ones we recommend to our customers.
Good equipment at a good price. I have used your products before and have had great success.
Works Great!
We love our MVP-50P w/ its crisp, intuitive display and ease of operation.
Keep it up. I’ll keep coming back.
Safety and simplicity!
