Chevrolet and GMC Panel Truck and Suburban fuel tank sending unit. 30 ohms. 5/16" line size. Complete assembly with gasket, sceen, and pick-up tube. Fits in gas tank.
30 ohm sending units work with original style fuel gauges up thru 1966 trucks. 90 ohm sending units were used on most 1967 and later trucks. If you are using modern gauges (Dakota Digital, Classic Instruments, etc.. ) make sure you are using a 90 ohm sending unit to get a correct fuel level reading.
