Here's the deal '73 fj40, aftermarket poly gas tank and chevy V8. As it stands right now, there is no ability for the tank to "vent" as gas is drawn from it. There is the filler neck and the outlet line to the carb, and no other ports to allow air in as gas is drawn out. So...if I don't leave the gas cap partially unscrewed, I get a vacuum created inside pretty quickly. I need to some type of charcoal cannister/gas separator, right? There are a couple of plugged ports to add additional accessories to the tank, just not sure how to go about it and where to get the parts.
Thanks for the help,
David
