Re: Fuel sender & 12V conversion on a 1953 Clipper.

On directly hooking the instruments to 12v: There were two different instrument voltage regulators used. 51-53 used one part number and 54-56 used another. I do not know what the differences are. It could be a matter of capacity since some 55-6 models have a third instrument running off it or it could be input voltage range. Why a different item was introduced in 54 to work the same instruments as 51-3s had is unknown. Some articles say 54 was the targeted major change year which was pushed back until 55 so maybe that anticipated change was the reason and it was a matter of stocking parts.
Point being that we know 54-6 instrument regulators can work on both 6 or 12v and I suggested changing to that item. Perhaps HA52 or others have done it and proven the 51-3 can also work dual voltage but if not, I would use caution if you are going to run your original instrument regulator on 12v.
One place that has done a few 6 to 12v starter conversions is Advanced Electrical Rebuilders in Grand Ledge, Mi. No idea if it is limited to specific models or the cost but if you can't find someone more local maybe worth a call.
