I used the newer gasket. I ordered 5 of both part numbers "just in case" as they dont cost anything.

The older gasket has 1 big hole where the filterneck connects with the valve body.
The newer gasket has 1 big hole where the filterneck connects with the valve body and a small rectangle shaped hole right next to it.

I have used that newer style gasket with 2 big holes more often in the past without issues.
