[DeTomaso] Fuel vapor canister/charcoal canister.

FWIW:
I ran my vent hose around the back of the tank, making a short dip on the
tank side of the heat shield so I could put the little, in-line overflow
valve in a vertical position (on the "upside" of the dip) so it would work
properly if the car ever flipped, but when right-side up allow proper
venting. I then continued to run the hose under the back window, but
because I like to be very conservative, I also added an in-line fuel filter
so dust and junk couldn't migrate into the gas tank, then the hose, still
running along the bottom of the back window, comes past the distributor and
carb and then around toward the back of the car, terminating into the bottom
of the air cleaner. And, because I like to be very conservative, I bought a
little foam flame-retardant item which is located inside the air cleaner. I
had to modify an adaptor or two to get the hose to connect to the foam
flame-retardant attachment, but it seems to work just fine.
And, because I like to be very conservative, I'm going to wait until I can
resolve the oil-burning problem my engine has before I try and take the car
up to 175 mph...
Sincerely,
Chris
