That's a nice diagram of the bulkhead fitting...I have stored that one on my computer for a future arb install link
. As said earlier, you can get those fat grommets from arb directly their number is 1-888-427-2872 They only cost about 10 cents each so might as well get a dozen for you and your buddies. I tried my best to find an equivalent here in Chandler at Ace super-stores and good ole TrueValue and nothing is that "fat".
