1952-59 Ford fuel tank sending unit capacitor connections

I took the sender out to replace it. There was what appears to be a capacitor connected to the sender. There is a spade terminal for ground and the stud with nut and bolt for to connect to the gauge. Where does the capacitor attach? I think to the stud for the gauge wire. Is that corret?

 

Unfortunately I don’t have an answer to your question. I’m not sure why there would be a cap in there at all though? The wire that runs up to the gauge provides variable resistance doesn’t it (hence the level reading displayed on the gauge)? Doesn’t seem like a capacitor would have any role there…

 

No capacitor on mine. Maybe somebody with more electrical savvy than me was trying to adapt a different range sender?? I don't know what a capacitor does actually, lol, so just a wild *** guess.
Tanks Inc has a good section on sending unit troubleshooting.

 

There was one on mine. It was smaller in diameter and longer than a standard ignition or generator/regulator capacitor. I did not check its values and it was not on the print I had. It attached to the ground. When I changed my sender there was not one on the new one so I felt it off.
I believe, just a guess, it was for protection to bleed off static electricity. This was Fords first m*** produced 12v car.

 

These typically were used for radio static control

 

This makes sense. My car did not come with a radio from the factory and it doesn't have the capacitor on the fuel tank.
