Next job is one of the fuel tank gauges is displaying full even though the tank is half full. I expect a new sender unit is required.
Guess once you done the first you also have more confidence in what you are doing, I did miss the hours not showing and it was only when boat had its annual service would I know the actual hours,
I had a fuel tank gauge that at certain levels would jump between empty and full, But would then settle down to approx what was in the tank,
I do know of a friend who very carefully calibrated his fuel gauges and knew within a Gallo or so exactly what his tanks contained
