where is fuel gauge sender located in the vehicle?thanks

Mounted on top of fuel tank..

the sender/float arm/switch is inside the fuel tank and is part of the fuel pump module assembly,not sold separately. best to replace the module assembly. the tank needs to be dropped/cleaned prior to install. copy and paste the link below for best price,compare to local rip off parts stores! https://www.rockauto.com/en/catalog/chrysler,1994,new+yorker, 3.5l+v6,1066092,fuel+&+air,fuel+pump+&+housing+assembly,10147
