Being that I have a vented cap, are both holes needed? I know about the filter (ground up has them). I am looking for a solution until I am able to get the piece as I am having the car tuned tomorrow. I have read that some of the members capped the small vent tube while running the hose off the larger tube up towards the body, inserting a small fuel filter on the end to keep anything from getting in and then running a small piece of 3/8 off the filter towards the pumpkin incase any fuel did manage to escape.
