We'll I just keep the other cap for emissions. I've been doing a little reading and the general opinion is all 72's came with emissions. When I came home I checks and this truck never had a charcoal canister, the fue tank doesn't even have the lines on it. There no signs the tank has evey been taken out. The orginial owner never changed anything on this truck, so I trying to figure this mystery out. All it's had is a PVC....no cat, no air pump....could this be
