I’m having a hard time identifying a Cessna part number and where it came from. The fuel caps on my C182 have the part number of C-100084-1 printed on them but I cannot find that number anywhere in the parts manual. Does anyone recognize this number or know if it was superseded with another number?

It's the Cessna fuel cap part number. C156003-0101 is the new number. https://www.mcfarlaneaviation.com/products/product/C156003-0101/

FYI I just changed out one of these seals on my 182 fuel cap, as it was loose when closing. As I was installing it the seal, I noticed the hex screw in the top of the cap was pretty loose, that was the real cause. I changed the seal anyhow, but wanted others to be aware to check the screw first.
??? FYI: I believe the C number is a sub-part of an assembly part number which is what is in the IPC.

Do you need the whole cap or just the gasket to refresh it?
Thanks for the replies guys. On the eBay listing, where the cap says C156003 mine says C-100084. Same spot and same printing.
As stated above 003 is the superseded number hence the 084 number in the ad. A quick call to Textron support will clarify.

The right gaskets with the slip ring are important, plus the hex nut on top of the needs to be adjusted for proper tension. Good to have a knowledgeable A&P help with a log book sign-off. If there is every an incident involving fuel, this is an area the feds seem to always investigate since almost all Cessna 100's have a fuel cap AD.

Thanks to this thread I would up finding the kit at McFarlane cheaper than just the single gasket elsewhere. https://www.mcfarlaneaviation.com/products/product/FC-KT-1/

Work with your A&P to tighten the cap to proper tension. It's a quick job that requires a log entry, especially since proper cap tension is part of the fuel system AD for nearly all older piston Cessnas.
Bell206 was correct on this one, C-100084 appears to be a sub-part number. Ended up replacing the old cap with a new one part number C156003-101. On one side of the new cap was the C156003 number and on the other was C-100084.
