Re: 72 K5 EFI upgrade & evap canister woes

I am not sure that it would pressurize with a vented cap, but that's where I get hazy on this part. I will have to pick up a new canister, as I do not have that. Just the original lines that run across the rear cross member next to the gas tank.

The EFI system runs a single 02 sensor, so I am thinking it could account for the collection of fuel in the canister if that were an issue.
