[DeTomaso] Dumb Techno Question: Charcoal Cannister ?

[Asa Jay Laughton]

The rollover vent valve I used was recommended to me by a fellow Pantera 
racer.  I bought it from Pegasus Auto Racing:

In the photo below, it's installed in a length of fuel line from the 
vent valve on top the tank, routed down beside the tank between the tank 
and the fender, and then back up so the valve itself is significantly 
above the top of the tank and secured to the inner fender with an Adell 
(sp) clamp.  In the case of my car, an L model, the engine trim piece on 
the drivers side hides this very well under the bump for clearance of 
the tank filler tube.

I've had no fuel starvation problems, or spillage issues.
