Dry Sump reservoir Caps?

Hi Dry Sump people. I am curious if anyone is using a different reservoir cap than the ones provided with the Peterson Tanks. Here is a pic of the one that comes with it.

If so what are you using?

I was able to find an off the self oil filler cap that works from NAPA. It has a completely different look but does the job. It also doesn't hurt that it is $5 instead of $43.

Ps- to be transparent.....I lost my original Peterson cap and needed something to cap the tank.

That Peterson looks like the same cap that came with my Lee PS reservoir. Should be fairly universal to find. Glad the NAPA one worked for you tho.
