Fuel System: Correct ohm range for fuel sending unit?

[airmanjwt]

Any body know what the ohm's range for a 62 gt fuel sending unit? Doing a mild custom and would like to use modern gauge package. airmanjwt@gmail.com

I think the old guages read 0-244 ohms or thereabouts. The new SW guages are 0-90 ohms. You will need to match
the sending unit with the fuel guage.

Sorry, neither are correct for Independent Makes with SW Gauges, these must be the common GM type OHM ratings.

It's 240 Empty 33 Full that you need!

Measure your Tank depth, there are several. This one is for a 6 to 12 Inch Deep Tank.

Here is the Hawk Style SW Fuel Gauge:

Rich is correct. 33-240 ohm; standard for Stewart Warner, Auto Meter and many other generic gauges. Classic Instruments makes fuel gauges in almost any resistance you might need. I just replaced my stock fuel gauge (and the other small gauges) with gauges from Intelletronix.

What is the opposite to OHM?

[Dwight FitzSimons]

The opposite to ohm is mho, the inverse of ohm. I.e., 1 mho = 1/ohm. Seriously.
