Thanks, Oz,
I've got a PM in to Eric already and he's looking in to some options for me, and I also spied an option at nastyperformance.com if I can get them to sell me piece of their custom tank separately. I would obviouly prefer a better o-ring, but whatever it takes I guess. I think I'm hooked up on the pump and tank specs, but let me know when you find one so I can bounce an idea off you.
