Got a question, this is going to be on the original engines. When installing the 440 in our cars, did the factory use the vapor canister over the fuel pump like used in the GTX and RT 440-Hemi? If used, then there would be two lines running to the tank, 3/8 & 1/4. Mine only has one 3/8, is this correct? I guess I'm asking, where those canisters omitted on these cars with just the line between carb and pump?
