Sharpe,
The tank isn't rusted. The reason for the pin hole is that I modified a (new) '69 camaro tank to fit and I brazed a support for the pickup tube to the bottom of the tank. But when I brazed the support I must have accidentally burned through in one spot and that's where the gas is leaking. Next time I know to solder the tank and not braze it
. I will check the filter and pump as you suggest while everything is out. Thanks again for the help!
Mike
