Hi guys, I'm sorry to even bother with this question because I'm almost 95% sure I'm right to begin with... But anyway, my buddy says you need a low-pressure HPA tank to work with the Tippman LPK kit... I've never seen any of the sites that sell them mention this, and thus assumed that it would work with a high-pressure HPA, since isn't the pressure regulated down as part of the LPK anyway? Just wanted to check...

You will have to get a secondary regulator with the LPK (not supplied with the kit) to bring the pressure down to the needed range even if you use a High pressure preset HPA tank the xtra reg will bring the pressure to where you need it. If you get a preset Low pressure HPA tank you can only use it on low pressure markers. So get the High pressure preset tank so if something goes wrong with the LPK you can put your old internals back and use high pressure setup. If you get the Palmer Stabilizer (reg) you can use it for High and Low pressure.
