Charcoal Canister Delete?

[Huw Powell]

Yeah... the only "original" "vacuum hose" on my 82 Coupe is the one 
going through the inner fender to the charcoal can.  While I guess 
deleting it might seem easy, where do I run the fuel tank vent line to then?

By the way, during the comparison to airplanes and altitude-related 
"pressure in the tank" issues, I was thinking that it is still an issue 
with cars - not so much to balance the tank and carburetor, of course, 
but to cope with the expansion and contraction of the air in the tank 
(and to a lesser extent, the fuel) due to ambient temps, which could 
easily run 10% over a 24 hour cycle.

Of course it's rare to see a pre-OBD II car where the system still works 
properly and completely (maintaining a light vacuum in the tank), 
although a new gas cap may be all they need.  OBD II cars will throw a 
code and light the MIL if it's not working right.  Hmmmm, maybe I should 
smoke-test my gas tank one of these days out of curiosity...
