As I am finishing up new fuel lines, with clean, empty tank, it seems like the tank holds a slight pressure, when blowing thru the return line. I'll be using the bosch 044 fuel pump, which moves a lot of fuel, and want to make sure there is no pressure fighting the flow back to the tank. Does the stock '75 cap have any self venting property's, or does all the tank venting go thru the TINY vent port, that heads to the charcoal canister? If so, have any of you added a bigger vent, as a fuel cell would use? Thanks, Tom
