The issue is the Ricks tanks and most aftermarket tanks do not have room for expansion.
This one of the only issues we had with Charlies new Riv.
The 2 Much canisters do a great job with fuel vapors but no pure fuel.
I may add an expansion tank to the project before the 2 Much canister to keep raw fuel out of it.
Thanks for the comment I almost forgot about that.

I’m going to humbly disagree with Mark. The older version of the Rick’s tank uses an internal manifold/tube which may cause the tank to pressurize and push liquid fuel out of the vent port when full . The internal vent tube seems to act like a straw that can submerge the vent port in fuel when the tank is full. Newer Rick’s tanks appear to have abandoned the internal manifold and switched to a two port design. A port on the filler neck and one strategically placed on the tank running to a T and then to the VSB or VSR has worked well for many II MUCH customers even in road race applications.
The Riveria also had the internal manifold design, and overflowed as I predicted in conversation with Sled Alley after I saw a picture of the tank on the build thread.
If you scroll to @motobrewmaster ‘s post in this thread you can see one of the older Rick’s tanks modified as described — he plugged the original port location on the front of the tank and added three new ports. Three is probably overkill but certainly can’t hurt.

That said, Mark took a sledgehammer to the problem and is happy with how things are working for him. I’m happy to continue this discussion with anybody that is interested privately.
