Question Lost fuel cap

I flew from Fort Worth, TX to Orlando, FL overnight. One of the crew memebers notified me after a day that one of my fuel caps is missing. I usually take a extra fuel cap in my plane kit but this time I forgot to bring it after reorganizing. What are my options? I need to fly back tomorrow. Anyone close by I can pick up a fuel cap from? Or just put some tape and run with it, calculate for just one tank 😬

If you can't find a fuel cap, you might try a pool store. They carry expandable plugs that fit different sized holes. Sure, it'll be ugly, but will probably work just fine for a day or two.

You'll need to know the internal diameter of the fuel filler neck to pick the right plug.

Default Missing cap

I would also try to burn as much from that tank first, incase the tape or plug fails and starts to siphon, you'll get as much out before you lose it!

Tried that once. The tension pin in my cap broke while getting gas. Sealed it all up well with duct tape. Before the end of my 15 minute flight, gas was streaming back on the wing. Gasoline will break down the tape's adhesive very quickly. It was a gummy mess to clean up once the gas evaporated.

The plug idea is a good one, with maybe some duct tape to help hold it in.

big box hardware stores also carry those plugs used to test new shower installations for leaks. Should also work if the size is right.

That is why I never had my N-number etched in the fuel cap.

With my luck, it would come out in flight, and fall through a fancy stain glass window or something like that. Just fuel type and quantity for me. (If I was to have them milled again, they would say "94 OCT MIN - 18 GAL" instead of "100 OCT - 18 GAL"

Been there done that, "speed tape" (aluminum tape) was a quick easy fix, worked like a charm. Switched to locking fuel caps after that. I always carry some in my tool bag. Most mechanics keep a roll around.
