This is the sending unit that measures the amount of gas in your tank and relays the information to your gas gauge. BROTHERS sells only complete sending units that come with the float and gasket. This sending unit also can be used with the 67-72 blazer gas tank conversion so that you can use your stock fuel gauge (0-30 ohms).***This unit uses the lock ring if you have a screw in type it won't work**

I have stock tank and stock guages, is this the baby I need? have read about 0-30 ohms, 90 ohms . . . confused . . .

Thx,

Roy
