More tank and oops fittings

Started making a new handle for the fuel shutoff valve. Had some scrap from the canopy that will work fine as a torque tube, and made mounted it to the valve with an angle so that the torque tube is in the center of the valve rotation. I'm not exactly sure how long it needs to be, and I need som descent looking knob, ut the function is OK.

Looking closer at the 1 inch oops fitting with the O-ring removed, I found that it was maybe 1/2-1 mm too close to the sight tube outlet and touched the protruding plastic on the inside. There is enough space on the inside to cut the hole at least 2-3 mm farter aft, but that is impossible to know up front. Using the sight tube outlet is probably a better choice? who knows. Filing off the oops fitting a little solved the problem.

Fuel valve, part II

Decided to simply fix the Airward solution so the moment only goes to turning the valve, not bending it sideways. It should work if I handle the valve with care, and if it starts leaking somewhere down the line, I have "installed" the Airward kit for removing the glareshield and wind shield, and can fix things IF that happens.

One thing I saw when I was finished, was that the weight of the fittings would close the valve during high G maneuvers. It would go to a half closed position (theoretically, I doubt it would actually do it due to the friction in the valve). I thought, oh no, gonna do it all over again, but then I remembered the big, red "Airward knob". It balances the fittings almost perfectly and acts in the opposite direction. So everything looks good (hopefully, unless the fuel level probe crashes).

I also primed the whole thing. Things just looks much nicer and "aircrafty" when primed.
