I found what I believe to be the closest Stewart Warner sender(280EE-F) available. It is a 140-320dg sender, my SW gauge is 150-350dg. $20 shipped from ebay so it's worth a shot.

Installed the new SW 280EE-F sender and that fixed it. I tested the resistance of the new unit and compared it to the old, about 73dg yesterday, new sender was 8200ohms, old sender was 2300ohms...with the resistance decreasing as they warm up...
