[DeTomaso] Dumb Techno Question: Charcoal Cannister ?

One moreŠ

I ran for years with no vent, but I had a Permacap from Hall.  The
permacap has a spring loaded flapper.  You shove the gas nozzle on the
flapper to put gas in the tank.  When you remove the nozzle, it springs
shut.  So, as gas empties, the flapper allows air to enter the tank, and
there's no suction in the tank.  When it gets hot, I'm sure it pressurizes
the tank somewhat, but it never seemed to be a big deal.

I don¹t have a permacap anymore, so I'm going to reinstall a vent, but I'm
putting the vent up high.  When I installed the rollover valve, it wasn't
sealed well enough, and it dumped gas onto the ground.  Not fun.

And the charcoal canister is for pansies that don't like the smell of
gasoline in the morning.
