Gary, It's an easy install. 2" hole in dash, the fuel flow transducer goes inline in your fuel line after your fuel filter (between filter and engine) in an upright position. Hook up pos. & neg to your 12 volt system and you're good to go. The toughest part is the hole in the dash.

It seems to be pretty accurate but I really don't have a lot of time on it. I would say it's within their claimed accuracy of 5%. It is supposed to able to be calibrated by the user to within 2%.
