Gas tank sending unit

[72k5mike]

Howdy,

anybody know if the sending unit from lets say a 78 blazer will work with the guage from my 72 blazer? I am looking at using a 31 gallon tank with proper sending unit to replace my stock 21 gallon tank.....


is there a way to check resistance?

Should be the same resistance most are standard 33-240ohm. The problem might be going from different size gas tanks. But the sending unit should work with the gauge, if you end up needing a different sending unit you can try one of these, they have both the 2 and 3 wire. Easy to fab it in.
