Update 8/21/2013:
I think I've sourced the reg, solenoid, pump and pressure sensor. I'll be home in 2 weeks, so I'll begin picking up/ordering components, fitting, and working on the circuit then. Something I'll try out while things come in is to try out a few sections of my modular barrel.

Update 8/22/2013
I sorted out the flow diagram (no pun intended), and I've removed the regulator from the design. I realized that since I was already adding sensors, I could regulate the flow electronically rather than mechanically. 

Coming Summer 2014
