fuel cell question

Check the vent tube and make sure it's not plugged - I would have to think it must be if it pulled vacuum. Bees and spiders come to mind.

I checked that, it was good. The fitting the vent is hooked to is the one with the check ball. With that said, if I shine a flashlight down that fitting, I can see the checkball, its at the bottom of the fitting but I can not get any light coming into the tank? It's like it is sitting on the hole, so basically the tank is completely sealed from any outside air, ball will move so in a roll over I am assuming it would move up to block the vent.

Buy a new cell and check valve. There is probably trash/debris/ fuel cell foam that is sticking that check ball. Years ago I had a bracket car that kept trashing and sticking the carb needle/seat. I finally pulled the fuel cell out where I could get a good look inside. Was a lot of crud in the bottom.
Good luck!
