Fuel sending unit.

factory cars used the 5/16 and 3/8, depending on whether a slant, SB, or BB. the 1/2 would be an all out race car.

finding the correct unit is simple, be it feebay, rock auto, or your favorite mopar repop parts hawk. the price will vary by the co, that made it as well as quality,, as is the same in the repop gas tanks.

yes it will be cold and maybe even snow here in MO by mon=tue.. been a dry winter so far, need the snow. not the cold!!!
