Been reading the threads about the difficulty with putting gas in the tank due to the filler pipe entering the tank half way up instead of at the top combined with vent issues. It seems there are two kit supplies tanks, old and new. My kit was delivered 2/18. Do I have the new tank? How big of an issue is this? Seems a good solution is to tap a vent pipe on top of the tank to the top of the filler neck. I need to remove my fire wall behind the driver's seat to redo something, so if this venting solution is a must do, this would be a good time to pull the passenger side firewall too, pull the gas tank and add a vent line. Should I add the vent pipe or is it not a big deal?
