My gas cap was unremarkable in appearance, it tightened up as it always did from new. It threw an evap code last year right before it was going for tailpipe sniff, ‘twas quite an adventure for data repopulation. Anyhow, my point is this: Just my opinion here but about a decade is a good time to preemptively replace the fuel cap. We don’t live in the era of “metal twisties” on a hinged clamshell mount where “ good” “meant still mounts tight and doesn’t leak fuel”. They aren’t expensive, so especially if I lacked the durametric for resets I’d replace it in or around that timeframe. Also, after long sits, ( a couple winter months or more) removal and resetting of the gas cap will only help. Weather cycles in the storage area can have an effect. In the south tire pressures and our caps are susceptible to dramatic shifts from this phenomenon.
