I have a MF-180 with the Perkins AG4-236 engine. Its a 1967 year model. I'm looking for a sending unit for the fuel tank. My parts book shows the number a 511 968 M1. I have not had any luck finding one on the web as I'm sure the parts number has changed once or twice in the last fifty years. Does any one know of an after market unit that I can use? I have found several after market ones but not sure if the screw holes will line up with the original ones. The ohm spread is correct for the dash gauge but after market ones don't give me the flange and screw dimensions.
