I had an F-Body somewhere but I think we might have scrapped it.
I think I am getting closer though. I finally figured out how the Jaguar's evaporative emissions system works. (The Jag is the car I put my LS1 in.) The Jag has a fuel vapor recovery system similar to the F-Bodies, however rather than run some sort of computer controlled EVAP purge valve (like the LS1) it runs a constant light vacuum in the charcoal canister at all times.
Under the worst scenario, I think I can just hook up the whole Jag evap. emission system to the LS1 by running a line from the Jag's charcoal canister to the LS1 intake with an inline restrictor to reduce the vacuum in the charcoal canister.

FastKat.. I dumped the LS1 EVAP.. I am just using the oem Chevelle Charcoal Canister. I just used the port that the EVAP was on to use as a vacuum source for the Charcoal Canister... as you said you might do.. Have not had any problem it running it this way so far.
