I am converting my 1946 Chevy Suburban School Bus to 12 volt using the voltage reducer Jim Carter sells.

It is specifically sized for your fuel gauge @ 1 amp.

The Jim Carter part number is EL311 which is a one amp "Runtz" voltage reducer.

I have one of these but have not put it in yet since I am still doing body work. I have just started refacing my gauge assembly.

While we are on the subject, where should I place this reducer?

I am guessing that it should be on the power input side of the gas gauge to step the voltage down to 6 volts from 12. Am I correct?
