Does anyone know the size o-ring used on the fuel sump drain?

Check out the ACS catalog pages on Fuel Drain Valves. There is a listing of "Replacement Seals" for the different drain valves....less that 20 cents each.

I had ordered some for my long-build time RV project, just to have ...incase. Each came in a hermetically sealed envelop, with a date stamp.

Glenn,

There was a thread on VAF not too long ago that provided this info:

Specifically, take a look at post #12:

Aircraft Spruce Sells the drain valve and the o-ring. I ordered a spare valve and some spare o-rings. I tried to look them up on their site but the pdf file that they are on is corrupt and will not display. Type in the Vans part# CAV-110 and it brings up the link to the bad pdf. In the 2006-2007 catalog they are on page 163. The part number for the o-ring is MS29513-006 $0.18. I had to replace mine as soon as I started filling the tanks after the years of building.​

Here is the size, as per Aircraft Spruce catalog:
