Default Fuel Tank Quickdrain: Repair or Replace

after almost 10 years, one of my quickdrains on the tank has developed a slow leak that I need to address. I see Van's sells both a full replacement and just the o-ring. My question is the o-ring likely the only issue and replacing that will likely give me another ~10 years or am I just better off replacing the whole thing?

whatever I do I'll do to both sides, so it's likely saving only around $30 to just do the rings but I'd rather spend that on avgas if full replacement doesn't gain me anything.

There’s little that can go wrong with them except the O-rings. I have spares on hand so if I have a leaky, I replace it, then change the O-ring on the “bad” one and put it back in the spares drawer for the next time.

No, it doesn’t happen on the same airplane vey often - I just have a lot of planes to maintain.....

Repair it with a new O ring and put in your travel tool bag. Buy a new one, they’re cheap to put on the plane. That’s what I did.
I also carry a spare filler cap with me as well you never know.

Default Both - Repair and Replace

Order a new quick drain and a few o-rings from Van's.
Install the new drain, then repair the old drain and replace it in the other wing. Then repair that quick drain and keep it as a spare. I carry the spare in the airplane.

Cheers, David

Like others said.

Plus: There is no need at all to drain the tank to swap the quick drain. Unscrew to the last couple of threads, then quickly remove, place a finger over the hole and either thread your spare in quickly, OR have your spouse just hold her finger there while you swap out the o-ring . "It will just take a couple seconds" might work for you...

Thanks guys! that's a good idea to buy one replacement so I can throw one in the tool bag. it will also make the quick switch easier having one all ready to go. I'll order 1 replacement and a few extra o-rings.

Since you are ordering now, another good spare part is the pin/repair kit for the gas cap. Those can also break and leave you stranded. That is another recommended item that is nice to have in the spare/repair kit.

Buy an entirely new gas cap, not just the repair kit. That way, if a cap comes off in flight, you have a spare.

Exactly what I did and it works great. Just get everything laid out and within easy reach. (I put fuel lube on my quick drains before I started.)

Cool tip? use your cleco pliers to hold the drain valve open while you swap out the o-ring.
