I was steered to that part after reading a note in the "Reviews" section posted by "Robin V" (formerly of Newton) on the "AERO 300 - A30 LOCKING AND NON-LOCKING FUEL CAP" product page.

According to my Spruce order history, this is what I bought:

The one you linked appears to be the one with a lot of curvature to the flange.

That's interesting. I did not check the diameter of the ER skin holes against my caps.

I included two links in my post. The first link I posted is the same cap you bought.

In these pics you can see that the Newton caps I bought (details above) Are smaller in diameter than the hole in the ER tank skins, but that there's a ridge, unlike in other pictures, and the overall difference appears to be less.

That ridge should allow me to fill the empty space with a decorative bead of Proseal or some other flexible sealant like Silpruf (not sure if that's fuel proof).

Are you sure? The part number appears different.

Default Cap

The more commonly used cap, not necessarily on RV's but on many others, is the Usher cap. Available with flat or contoured flange. Been around for decades.

Quite true and itís what we had on our RV-7. If you have ever used a Newton cap (OEM on Cirrus, Diamond and others) - you would never want to use an Usher cap again. The Newton operates with a gentle finger pull - no prying with a fuel strainer screwdriver or other tool. Much better engineered mechanism than the Usher in my opinion.

My 7 had the Newton caps. I took one look at the ushers when they arrived and put them in the cupboard. As Krea says they are a step change up from the Ushers. You’d never go back.
My original 2017 vintage RV10 skins were punched for the usher caps and I again used the newtons.
Sometime after then Vans changed to the SPRL and the hole got bigger.
I’ve actually got a cupboard full of usher caps and flanges I’m sure they are worthless but someone local will lose one one day and I’ll have a spare for them!

These caps are a good example of the incremental improvements that Vans has made over the years that mostly pass people by unless you’ve seen/tried all flavors.
The SPRL flange is a beautiful machined, anodized and pre drilled flange that fits the tank curvature perfectly. No tweaking or filing of the flange. It’s literally impossible to mess up.

It's A30LS vs. A30LR.

My understanding is the only difference being locking vs. non-locking, but maybe I'm mistaken?
