Stand beside the leading edge and reach under the wing to the drain valve instead of getting under the wing and reaching up to the valve. This will prevent fuel from running down your arm and letting you wear "Oduer de 100LL" the rest of the day.

I typically use a 1" finishing nail. It is about 1/16" in diameter, fits through the holes and allows all the time one needs to swap o-rings.

If carrying a spare quick drain in your fly-away kit, be sure to also include a little ziplock baggie (or similar small container) of your NPT pipe thread sealant to apply to the threads of that quick drain before you thread it into the tank.

I've found a little ziplock baggie works fine - lots of things we buy these days come with a tiny bag of parts - these little bags are just the trick for a tenth of an ounce of thread sealant.

Indeed! Common sense comes fast to some, not so much for those that just watch their elbow drip blue liquid .

I think I've stopped at least a half dozen people from draining a whole tank just to swap an o-ring. "But I have to drain the tank in order to...."

This is a great thread.

I would vote for the whole thing. Take a closer look at the drains. If you fly a lot you exercise them very often. I replaced mine after 7 years they rusted away and stems were too wobbly. I burn a fair amount of ethanol laced gas. Get a pack of O-rings and replace them every condition inspection they are super cheap. If you carry a spare you will never need it

As others have said...buy a new one and replace the o-ring in the old one for a spare.

When changing the drain keep the filler cap on and plug the air vent. You will have very little fuel run out of the drain hole as you change the drain with the vent plugged.

Tie a rag around each wrist. Loosen the drain and quickly put your thumb over the hole as you pull the drain out. Remove your thumb and quickly install the new drain. Remove the tape or rubber cap or whatever you used to plug the vent. Remove rags from wrists.

Default One more tip

I bought three replacement O-rings and changed them all.

My thinking was that if they were old enough for one to start leaking, the other isn't far behind.

Kind of like changing head lights, I replace them in pairs as I have learned that if one burns out, the other isn't far behind.

Do not over torque the drain valve for fear of splitting the aluminum flange!

This is a great thread.

Side note/thread drift.....sort of. I change out water heater elements without draining the tank. Just shut off the water, bleed off the pressure then make sure all the faucets are off. Have the new element at the ready. Jerk the old one and shove the new one in. I may loose a tablespoon of water. If the tank can't get air, it's like trying to pour gas out of can with no vent.
