Has anyone used one of these as a replacement for the fuel tank sending unit on any Bolens machines? Specifically, I want it for my 5120H Duratrac GT2000. Unless anyone knows if I can get an O.E.M or equivalent. These look nearly identical but I don't know the dimensions. Mine has a five bolt pattern that has a spread of approx: 2" on center. I figure the float rod can be shortened to fit the application.
