Does anyone know the value of the capacitor mounted to the original fuel gauge sending unit on a 1955 crown vic?

I am pretty sure that it is only there for radio interference and that the sender will work properly without it. Alan S. Freeman

I think it's purpose was to stop needle movement when turning corners and such. Kept needle readings more stable.

I agree with Alan. The capacitors were for radio noise suppression. The would also be located on the generator. You wouldn't have them on a radio delete car. The design of the sending unit and the gauge were so to prevent rapid fluctuations due to the gas moving during driving.

I just reviewed a 1954 Ford Radio Owner's Manual and it contains a Parts List. Included in the Parts List is "FDA-18871-A" described as "Condenser Assy.-Radio (Fuel Gage)". This is proof that the condenser on the fuel gauge sender is for radio suppression not needle stability. Alan S. Freeman

Here is a partial scan of the installation document for the radio receiver FDR 18805-E for 56 Ford
There are several condensers used for noise suppression even a spring to insert inside the dust caps for the front wheels

Thanks guys, great information, not worried about radio suppression so will leave as is.
