Thanks guys. It’s kinda crazy because I’ve tried the Napa 1100, it fit in the canister but the gasket was too large. I’ll look for a Krawlinater k55a since the picture Kevinski posted looks to be the correct gasket and you get different size gaskets. The others, Wix 51006, Wix 15017 may also work if the center hole is about 9/16.
