Default 2004 Check Valve Replacement Size

Finally got around to replacing my rear Check Valve - turns out the rear one -on my car- is smaller than the front one
the number on the smaller one 12565503
the number on my new one which is the same size as my front one is 22040805
anyone know if they are interchangeable
Thanks

So far as I know they are interchangeable, but confirm the female NPT thread size between the two.. RockAuto does not list different sizes.

Good time to relocate the rear check valve to the passenger side of the engine so it can be easily replaced next time.
