I need a fuel sending unit that will work with a 1973 duster side mount
I needs to read 240 ohms empty, 33 ohms full electrical and work with sun pro
gauges.
I don't remember off hand what the stock resistance is for this (a stock sending unit) sending unit. The reason this is specific to the Duster and not the other one you linked to from Summit is the fact that the sending unit and the tube that feeds the fuel to your motor is one piece. The one you linked is only the sender and, as I mentioned, needs to be top mounted.
