in one word, no...........
i have bought several, and although they have seemed to have the required ohm readings at full and empty, and will give those readings while manually maneuvering them inside the tank, they don't work as such when the tank is filled with fuel.
my one buddy just purchased one of those $80.00 "meter match" gizmo's for his boy's ramcharger with an aftermarket tank and sender, and he says that fixed it right up so the gauge on the dash reads correctly.
