What is the port on the bottom of the Evap canister supposed to hook to? I have three hoses on the top and nothing is connected to the bottom of the canister, or is it a vent? My EGR valve never moves. I took it off, cleaned it out and tested it again but it still doesn't move with the engine hot and revving it up. My catalytic converter has been cut off and straight piped. I am getting about 10 miles a gallon and I want to improve that. I ordered a new catalytic converter to put back on. Also my fuel pump is oily around it, and there is a port on the bottom portion of the fuel pump that has a hose on it and it is just dangling down, is this just a vent also? The engine runs great and spark plugs are chocolate brown but I am just getting horrible mileage.
