Fuel Testing

Part of preparing for the first flight is making sure the fuel tanks and fuel lines are clear of any construction crud. While flushing the tanks and lines I calibrated the fuel gauges which required adding two gallons at a time to tell the computers how to accurately measure the fuel. I also checked the flow rate of the electric backup fuel pump. Here's one of the filters I used. I have a big stack of them and change them often.

Here's my temporary fuel shutoff valve that I used to fill the gas can for transfer and calibration. Not in the picture is my grounding wire to prevent static issues.
