Fuel Gauge Sender: Description and Operation
FUEL GAUGE SENDERThe fuel gauge sender attaches to the top of the fuel tank. A cam lock ring retains the sender. The tank and the sender uses a seal between them.
The sender has three pipes attached to hoses. One pipe is for the fuel feed line. The second pipe connects to the vapor canister. The third pipe is a fuel return line to the fuel tank.
Some senders use a short pigtail connector lead. On other senders, the connector attaches directly to the sender.
