My header tank appears to lose fuel even when the fuel valve is shut off, so its a good bet header fuel valve isn't sealing well. Over 3-4 days the fuel level in the header tank goes down slowly. No evidence of any big leaks but the area around the carb looks very slightly wet. Of course its hot here in TX so at slow leak rate I am sure most is evaporating pretty quickly. Anyone have a similar problem? Anyway to adjust the valve closure other than to just replace it?
Also, in my header tank doesn't seem to have an extension on the overflow line so I don't get the full six gallons and my fuel gauge never goes to the top. I have drained the tank and got about 5 gallons tops out of it. Can the overflow line be replaced w/o taking the tank out (e.g., through the fitting on the back of the tank). BTW, the header tank was replaced new about 6-7 years ago, by a previous owner, so the hardware is not too old. Any insight or advice appreciated. Best regards, Rich Green N3881H 415-CD
