A few people have already asked me for advice on how to make external tanks like mine so here's the basics.
All part# are references to the mcmaster catalogue
which has the cheapest prices on these parts, which could be quite difficult to source from anywhere else. Home Depot DOES NOT stock things at comparable prices or quality levels. eBay is sometimes a good source for strange parts like regulators.
If you are planning on using a bike pump or the stock pump to fill your tank you WILL NOT NEED to regulate the tank output because a bike pump won't be able to fill your external tank to levels that are unsafe for the gun to operate at. The gun can operate as high as 75psi without any issues, but a bike pump won't be able to fill the tank above that pressure level.
The minimum pressure level required for firing the magstrike is around 30psi.
The essentials you will need are
+ Push-To-Connect fittings
+ Push-To-Connect Coupler (to connect to and extend the tubing out from the inside of the gun)
+ 1/4" OD tubing part# 5006K35
+ Material to make a tank (PVC pipe with 2 couplers and end caps or something else like polycarbonate or PETG)
If I make a second one of these I may make a tank out of 2" ID PETG tubing because it's cheaper than PVC, easier to machine, and I won't have to hunt around for fittings because I can just make my own out of sheet plastic.
+ A 1/4-18 NPT Pipe tap to thread the fitting holes on the tank part# 2525A113
And if you want to hook up a standard bike pump to the tank you will need a tubing to stem adapter.
This will fit into the lockable output on any bike pump since it has the same OD as a standard valve stem.
If you plan to fill the tank with a motorized pump or compressor you will also need
+ A 0-160psi pressure gauge (you shouldn't fill a plastic tank beyond 120psi)
+ A Check Valve or Ball valve (so that you can disconnect the pump source from the tank without the tank emptying)
+ A Non-relieving air regulator with 0-90 PSI output adjust
Regulators meant for use with airbrush equipment won't work as they are only regulating the flow. Relieving air regulators are more common, but will slowly empty your tank.
HPA paintball tanks or CO2 tanks can also be used, but you will need a paintball tank fitting you can adapt to the tubing, and a paintball regulator that can regulate down to or below 100 psi. If it can't regulate below 150psi you may have to use a second regulator inline that can.

The little critters of nature, they don't know that they're ugly. That's very funny, a fly marrying a bumble bee. I told you I'd shoot, but you didn't believe me. Why didn't you believe me?
