Intake 4 96tacoma where the filter isnt mounted over wheel?

I'm a 3/8 valve, 1/2 line kinda guy myself. valves on the tank. just works best for anything i've worked on. if you want any kinda similarity between front and rear speeds, get some slowdowns.

I am gonna go with all smc half inch valves from here:

just wondering, can 4 of those be used at dump valves, or do i buy those seperate?

4 fills, 4 dumps = 8 all together. thats what you need.
