My RV-4's refit is rounding the bend to completion. I can barely see the light at the end of the tunnel. One of the remaining tasks is to calibrate the AF-3400 fuel level indicators. To do that, I'll need to accurately add 1 or 2 gallons at a time to each tank. I don't know the best way to measure the fuel though. I'm sure someone here has a good method.
Thanks in advance.
