Fuel Gauge Sender: Description and Operation
The fuel gage sender is attached to the top of the fuel tank. The sender is retained with a cam lock ring. A seal is used between the tank and sender.
The sender will have two or three pipes attached to hoses. One pipe is for the fuel feed line. The second is connected to the vapor canister. The third pipe
is used as a fuel return line to the fuel tank. On some senders, a short "pigtail" connector lead is used, while on others, the connector attaches directly to
the sender. For diagnostic information, refer to SECTION 8A.
