Really well made, fits perfectly and looks & seal very well. Easy to open, it will be a pleasure to use those over the standard usher fuel cap. I showed my set to a friend who was rebuilding his RV4 fuel tanks and he bought my set on the spot !! So I re-ordered a pair as I was not yet ready to install them on my RV6 fuel tank.

Note that this fuel cap will not work as a direct replacement for the locking fuel caps sold by Vans Aircraft. The machined fuel tank adapters suppied with the Vans locking fuel caps are not compatible. Rating would be 5 stars if it fit. There was no option to leave out the rating so I had to include it.
