A question about a gas tank in the trunk of a Model A. Should I put an inline shutoff first thing out of the tank? I plan on putting an inline filter close to the tank before the electric pump. I'm going to use a short rubber hose on each side of the pump. I could use a short hose before the filter and use any of the hoses to crimp closed for a shut off down line. If it is suggested to plumb one to the tank what should I use? thanks Bob
