My Quick drain fuel drain is leaking. I think I've read that there's an O ring in there that usually is the culprit. Anyone know offhand what size that is? Maybe I can find one over at Ace.
Anyone have a part number for a plug to screw in the sump drain? Might be handy to have on a trip if you find a drain leaking and don't have another drain/o-ring to replace it
After 7 years of building it never occurred to me that the O-rings would need replacement from just sitting in the parts bin. McMaster Carr Viton O-rings ordered
When replacing a drain fitting, I take it that you do not use any kind of sealant on the threads. No tape.
Just use the bare fitting, correct?
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".
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?

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.
