Now that I think about I think you are correct on the tank vent. I’ll add a overflow tank in the tank before the TooMuch canister.

Mark,
Overflow isn’t needed, but just one vent on the filler neck and one on the body of the tank, both lines should meet at a T fitting and then a single line up to the IIMUCH VSB.

The problem I run into with the vent hose hooked up to the filler neck is with a full tank when accelerating the fuel goes up the vent hose into the Too Much canister to the point it fills it up and overflows out thru it's vent.

Been there tried that. We added a 1 quart over flow tank in the trunk. It is the way highest point in the system. Then we vent off the top of that to the Too Much canister.

I’m sick and tired of the fuel puking out. It seems to work great. I fully filled my tank with very cold fuel and then parked it in my heated garage. No fuel smell and no signs of over flow.

Done. Fixed it. I hope. We will find out this summer.
