This OEM Part Worked Perfectly
I never buy cheapr knock offs and this was no exception. Performed the replacement about about a month ago now and it resolved my issue instantly. The replacement is super solid and fit right into the heater. I tried this on a whim instead of buying the full manifold kit, and this did the trick.
