Here are 2 demo videos which show possible setups that can be incorporated into various air tank blaster mods.
Safety Valve System - Parts Demo
- Topeak Pump (Mini Dual G)
- Pressure Gauge
- Adjustable Pressure Release Safety Valve
- Nerf Air Tech 3000 (AT3K) Air Tank Assembly
- M6 size Pressure Rated Air Hoses
- M6 size Pressure Rated Quick Release Couplers
You'll notice in the video that i'm using a Topeak Mini Dual G (2-stage/double-action) Bike Pump, it has a max. pressure rating of 120 PSI and it only took me 2 easy pumps to reach 50 PSI with the AT3K air tank (a magstrike pump would have required 6-7 pumps to reach that PSI).
Thats one of the reasons why i had to install a safety valve in my modded AT3K units, 'cos the pump effort is so easy and light that i sometimes accidentally put extra pumps into it and end up exceeding 100 PSI, which makes the trigger so difficult to pull that i had to open the casing to disconnect the air hose just to manually release the excess air pressure. With the safety valve i can set the limits or vent the pressure externally.
Anyways, after trying out various replacement pumps, i now use the Topeak Pumps for all my modded AT3Ks, it allows the blaster to operate at a much higher RoF and with alot less effort, so i recommend it (or similiar high pressure rated double-action bike pumps) for any modder who is looking for a similiar combo.
Here is what an early setup looked like (before i installed the safety valve, which is positioned at where the goo gauge used to be):
TP3k = Topeak 3k.
