My autometer 2242 oil pressure sender quit literally 3 days outside of warranty. It had maybe 3k miles on it. Replacement would be about $60CAD, not super expensive, but this is not a repair I want to keep doing.

I did some research, and found that the 2242 has a resistance range of about 240-33ohms, 240ohms being 0psi and 33ohms being 80ish psi.
So naturally I looked at various OE oil pressure senders and it appears that most AMC engines used a 240-33ohm sender with 1/8NPT fittings.

This looks almost identical to the autometer sender and supposedly has the same ohm range and only $20. I'm going to give this a shot and hopefully have a more reliable or at least cheaper alternative than the autometer senders, which apparently fail rampantly.
