So I know almost every nerf part inside and out, but when it comes to manufactured valves and hardware, im completely clueless. I need you people who know what you are doing *cough-captainslug-cough-angel-cough-split-cough* to help me out. Im almost certain every part i need exists, i just dont know what it is, what its called, or what its part numbers is.
Heres my pretty, colorful picture. the thin-lined little box is the part that will be revieled if the battery cover is removed. Each different hose (thick line) has a different color so you we dont get lost when they cross. If the picture doesn't make sense, read the descriptions below. (note that this is not made exactly to scale or anything like that. its just here to show what im doing)

The grey part of the stock has been removed, and replaced with the tank. only one side of the shell will be glued to the tank
(missing)=tell me what it is
(found)= i know what it is
the different valves are colored. here is the function planed for each valve:
Grey(found): Magstrike valve. Im so smart

Green(missing): a port where i can quickly connect/disconnect an extra tank if i need it, such as a backpack, or an airtank on my golfcart. A built in check valve would be nice, but if it doesnt have one built in, please list a check valve that will work with it
Red (missing): Regulator. I plan to drill a hole in the side of the shell, and poke the regulator out. I want to be able to adjust the power of it on the fly in the middle of a war. Im hoping for something similar to the switch on a RF20 (except a regulator instead of just a choke) where i can turn it to one position for high power, and another position for low power. (i do realize that if i decrease the pressure setting on a regulator, that it will not decrease the setting on the output side untill after the output side has been emptied. therefore, the pressure change, if it is a decrease, will not be applied untill the second shot)
Blue(found):3 way valve shown here
Light blue(missing): an input valve found on car tires and bike tires
Purple(found): a regulator for the ARSCB. Doom showed me a typical non relieving regulator
If you know what any of the missing valves are, tell me please
All help is appreciated
