Everyone I know has an auxiliary fuel shut off valve. Put a gas/fuel compatible ball valve under the dash in the line from the tank to the firewall. I suggest close to the tank where you can reach it from the driver's seat. It is fairly well hidden there; you can't see it unless you are under the dash lookin in that area. I have a 30 Cabriolet with the valve at bottom of the tank inside the car; I had replaced valves several times and which always started leaking after a year or so. I have the strainer in the tank but little rust particles find their way past it and spoil the already mediocre valve. The glass sediment bowl would fill in a few hours with the valve shut off. I gave up on it and added the ball valve. I always use the original valve, but if parked for more than a few hours, I will also shut off the ball valve.
