No start condition after running a while

They sell a return style fuel sending unit. You can buy that and leave your charcoal canister hooked up.

We just ran a hose to the vent line that comes from the tank that went to the charcoal canister over to the filter. The metal feed line came across in front of the water pump to the filter. We replace the filter and zip tied a hose to that line to see if it would work. Car runs great now.
