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

Here is the Packard sender. As you can see the arm has a slight bend and total length is just shy of 8 inches.
Am curious about your "small 6v power supply for the horns and gauges". The gauges actually work on 5v so if you keep the existing instrument voltage regulator in the circuit and run that off the power supply it should be adequate. You can also get a 54-56 instrument regulator from a parts car, vendor or maybe Mike Dulinski and power that to run the instruments directly off 12v, Some Ford instrument regulators will also work but I don't have a number for those.
Am more concerned about using a power supply for the horns. A pair of horns can easily pull 25 amps so "small" might not cut it but more importantly is if the power supply is rated for coils, motors or other inductive loads. Some are but most are not and any inductive load or something that has a large instantaneous current draw could make an ordinary power supply that was built for lights, solid state radios and stuff like that self destruct in a matter of seconds.
Also don't forget the heater blower and the stock radio (if you are keeping it). The starter solenoid needs to change and more importantly the starter motor is a concern. If you are planning on using the stock motor on 12v be advised that several posters over the last year or so have had the nose of the starter crack or break off suddenly for unexplained reasons. The only common denominator was all had been using the stock 6v starter on 12v conversions. It is surmised the reason for the breaking is because the extra voltage is providing so much extra torque and speed that it was slamming the pinion into the stop at the end of case hard enough to break the casting.. Some that went thru the experience had their starters converted to 12v to avoid future problems.
