Fuel Sending Unit Replacement Question

The new sending units are also crap. Definition of crap: They are constructed completely different. They have a different pivot point and a different length float arm. They have a different length tube. The scale does not register the same on the gauge, and it is off by almost half a tank. Best to repair the old one by hook or crook if you actually want a useful gauge. You can buy a new gasket, a new sock, a new float and a new ground strap (this is often the only problem).
