Classic Fuel Tank Sending Units 


Classic Instruments manufactures several tank senders to conform to most OEM (original equipment manufacturers) electrical resistance specifications. 

Classic also assembles many of its fuel gauges to read correctly when connected to the original or stock tank sender. 

A chart is provided below to assist you in determining what tank sender you probably have in your vehicle. 

Refer to the chart when choosing the proper resistance range of fuel gauge to connect to your specific tank sender.
