After I filled up the tank and drove home today, I discovered a fuel leak in the back of the car. Closer inspection revealed that the rubber hose that connects the fuel tank to the steel fuel line was slowly leaking fuel. So I spent a few hours draining the fuel tank. The replacement of the hose, 5/16", took just a few minutes. Since it is now easier to work on the fuel system, I am going to check the other rubber hose connections and replace them.
