Not sure if he sent me back my original gas gauge. Mine would have had to be 12 volt to work without voltage reducer. If this one is 6 volt then a Runtz should be a fix all for this problem? I got the same 1/2 full indication with the old sender and with the new sender. I did not take a sender at the tank reading of 30 ohm, was kinda assuming that since it was new it would work as advertised. May have to call Bowtie bits on Monday to find out what he used. Hopefully he will remember my exact refurb.
