What is "fuel lube"? Fitting wet down with fuel?

Think sticky Vaseline that doesn't dissolve in gas.

Thumbs up Fuel lube

I second that, fuel lube!
Keep a spare drain in your flight tool bag and a few extra prongs, you can get everything from Aircraft Spruce.

While your waiting for parts, find a friend to hold their finger on the open hole while you clean out the trash that is stuck under the oring. Then put it back together to stop the leak.

To greatly reduce the loss of fuel during the removal of the drain valve.....

1. shut off the fuel valve, or switch it to the other tank.
2. Have someone hold their finger over the end of the vent line. If you use tape, REMEMBER it's there....REMEMBER it's there.

If you have a good seal on your fuel cap, your loss of fuel as you remove the drain should be just about "O".

Did this several years ago with suprisingly minimal fuel loss - just be quick, but not too quick Slow is smooth and smooth is fast. Another good tip, and one that is obvious, but I didn't think of, is to wrap a rag around your wrist on the hand removing the valve. Prevents what little fuel that does come out from running down to your armpit

Recognizing it isn't an option on the road if you have a leaky fuel valve but if I'm at home base, I use it as an opportunity to drain all the fuel out of the tanks into 5-gallon jugs (strained). I figure if there's **** gumming up the valve, there's **** in the tank that needs to come out.

This is particularly an issue, I think, with those of us who polish, especially those who dust with flour after. It gets around the fuel cover and a few grains end up in the tank.

so my drain was leaking, I had a spare, and swapped them out. No big deal. I inspected the leaker, and found that there were some small debris sticking to the o-ring which likely was causing the leaking. I was planning to replace the o-ring and keep the unit as a spare since I had two extra o-rings but I can't figure out how to get the old one off... and putting the new ones on looks like it could be a trick too.

Any suggestions? Tips/tricks?
Thanks

I use a dental pick, the type that has a 90deg. bend. Not much concern for the old one, just go at it. On the new one, catch the edge on the flange, hold with your thumb, and then use the pic to stretch it over the other side. Just be careful it to nick the o ring. A bit of heat from a heat gun or hair dryer helps if it is cold.
It's easier than it looks.

Default fuel drain O rings

Harbor Freight Viton O-Ring Kit has many different sizes, and the smallest size just happens to be just right for the fuel drain.
