Fuel Tank Cover to Tand filler neck Gasket

[Bruce]

Have to find out if this is safe/legal/comfortable for the passengers, looks like it would make a good seal http://store.wagaero.com/product_inf...oducts_id=1936

Code 8 for experimental

Just keep AC 23-27 in your back pocket. I may have once seen a similar filler neck gasket having once been originally designed and manufactured for a John Deere tractor. The associated airplane didn't seem to notice, and last I checked, neither were flaming holes at the end of the runway... or then again, maybe it was an aircraft filler neck grommet that was attached to a John Deere tractor... I alway get those two confused...

Code 8 for experimental

Since it is for experimental only I should not confess, but I use these seals and they work fine. Nice and tight seal against the tank cover and no water or fuel collecting like on the thin rubber style. No glue or anything needed either.

My plan is to bond the gasket to the cover only. Doing this will allow tank cover removal without possible damage to the gasket each time the cover is removed, ie annual/100 hr inspections. It is my belief that, if the gasket is tight around the filler neck of the tank, small spills will be contained long enough to be absorbed with a towel before very much fuel could make its way into the wing.

I have the ones from Univair and they fit very snugly around the filler neck, as Gilbert mentioned. If I glued it to the cover it would probably tear the first time I yanked it off and I would never get it back into the correct position when I put it back on. Since my airplane lives inside I don't have the issues that JPerkins has with water ingress. Also, 100LL evaporates a lot faster than water!

Silly question maybe, is the filler neck gasket installed on top or under the tank cover.

Never mind, found the answer. Speaking of tank covers.....

I did some research on the fuel tank filler gasket recently. I am finishing up the rebuild on a 1982 model Super Cub that had never been apart. It had the sponge rubber gasket like on the bottom of a flapper valve seat in a toilet on one filler neck and the flat rubber gasket on the other. When I researched the part numbers for the Clipper, Pacer, Tri-Pacer and Super Cub they all came up using the flat rubber gasket. I wonder if that foam type gasket came from the J3 nose tank or something. These late model Lockhaven Super Cubs have some things that were not done coorrectly. Clyde Smith tells me their work force was retiring and moving the the new plant at Vero Beach.
