Most of the Drake catalogs state that the original sender will not fit their tank, and the Drake "universal" sender will be required.We have used that unit on 6 volt cars without problems, but they don't seem to offer different models for 6 and 12 volts, as do other vendors such as C&G. I assume you would have to at least add a series resistor for 12 volts to keep the gauge correct, as the 6 volt provides 10-100 ohms, the 12 volt, 40-180. Even so, it is unlikely the reading would be linear.

I was unable to locate a King Seely but did read that it works differently than the resistor gas gauge. It has a bi-metal strip that works in conjunction with the original gas gauge. Now I know whats been done ie: Tank by Tanks, Inc, sender unit from MAC's, and a 1/8"depth adapter plate to accomodate the six hole after market sender. I located an original used sender from a 51 Merc but the thickness of the 6 hole adapter appears to raise it too high in the mounting for it to make proper contact with the fuel . My next plan is to buy the C&G unit and hope for the best. As always , I value everyones suggestions as thanks again for your help. Tracker

I have used the sender from Yogi's with good success.

Almost always, the float arm of the sender must be carefully bent to allow the proper reading. It is done by allowing the fuel level in the tank to be used until it is nearly gone, the adjust the float just enough to touch the fuel.
