So I'm finally getting around to taking off my airpump after I installed Racing Beat back in the end of March (at college, yeah yeah...) Anyway, I'm going to go out to Home Depot to get the plugs that I need but I'm not sure what size they are and how many. I know that one connects to the air intake which looks like 1/2" but I don't know where else I'll need a plug. How many do I need total and where are they located? Also, with the Racing Beat hardware I have a small red cap and two bolt/washer/nut combos left. Any idea where the cap goes? Thanks.
