First thanks for all the suggestions regarding my "304 missing" yesterday. I'll try most of the suggestions soon. I filled up the tank yesterday and noticed a fuel leak with a full tank (naturally) so I started looking today. It turns out that the solder connection for the suction pipe on the fuel sender assembly is broken. This produces a crack where the assembly passes through the fuel sender plate on top of the tank. I pulled the tank today and emptied all 16 gallons of fuel. The tank looks excellent inside and out. I plan to re-solder the connection tomorrow but I am concerned about what the heat will do to the little plastic/fiberglass board which provides variable resistance to the fuel gauge. I guess I'll place a wet cloth on this area when I am resoldering. Any suggestions are welcome. BTW Pat Whiteside of the South Bay Amx club provided the Jeep number for the sender O-ring Part #J0941521. Thanks Pat. I will also replace the saran filter on the suction pipe and hope I can get one at the Jeep dealer. Joe Fulton Salinas, CA
