Does anyone know what the resistance range is for older Smiths fuel senders or gauges? I have an older Smiths gauge I would like to use in my build, but the sender I may need to use has a resistance range of 33 to 240 ohms. Thanks, Jim C.

Have a look on the ETB Instruments web page (www.etbinstruments.com) under the Technical section. There is a bit in there about fule sendes.

Regards,

Arnie.
