I like the flush fit of this cap. Nothing can catch on it. I've only had it a few weeks, but so far so good.

Specifications on thread size stated as 1 1/4"..... actually measure 1 1/2" ....DID NOT FIT 1 1/4" THREADED OPENING ! Could not use!!

Will these fit the Marpac stainless steel fuel fill? Part# FP010065?
It will fit if the cap threads are 1-1/4" - 11-12 NPSM-Straight.

Need a flush-mounting cap (or something close). How mush does this cap 'stick-up' ?
The height of the flip up is less than 3/4".
