Fuel sender information

[the head]

anyone know what the resisitance range of the fuel level sender on an S13 is i am going to change to all aftermarket gauges and need to know what fuel level gauge i need to order

Bump, I need to know the same question, as I orderd an Autometer fuel level gauge that detects from 0-90ohms. If it is the wrong ohms, could I add a resistor or would I need to buy a fuel sender from autometer? Thanks, Snail

seems that our senders are a 4-85 ohm so the gm style 0-90 ohm seems to be the best choice without changing to the universal switch
