What kind of signal does the fuel level sender send?

What kind of signal does the fuel level sender send to the cluster in order to make the fuel gauge move and activate the low fuel light?

The sender is normally just a potentiometer.

The fuel tank sender will show varying resistance based upon what the fuel level is. I believe that it varies from 3-235 ohms, but I'd have to look it up in the Helms manual.

really its ohms eh??

say you were to buy a fuel cell or whatever with its fuel pump, would it be fairly simple to wire a fuel level gauge?

I have a '94 Civic that uses the OEM fuel tank and sender with an Autometer fuel gauge, the hardest part was ensuring that I had the correct wires for the gauge.

Re: What kind of signal does the fuel level sender send?

If it's anything like older-model Civics, then the signal that enables the low-fuel light is DIFFERENT from the potentiometer that indicates the fuel LEVEL. There is a separate sensor (hence the separate wire running right from the fuel meter). This signal will be ON/OFF (+12/0V).
