Does anybody know if I can attach a water backpack to my gun?

[Poseidon2000]

Yes, you can. First, buy a solar shower, preferably 2.5 gallon. Next , get some plastic tubing and a hosing clamp. Cut the showerhead, then attach the tubing with the clamp. you could attach the backpack directly to the pump shaft, allowing the H2O to flow directly to the pc, but it could be tricky to attach. Finally, put solar shower in a backpack, and you're good to go!

Doorstops seem to fit well into the reservoir filler tube. If you can get hold of another cap it would be a more permanent (and reliable) solution to drill through the cap and connect it permanently.

An example of a solar shower backpack (using a doorstop as a bung) can be found here and another (not using a bung) here.

Camelbaks (or similar) are very good as backpack reservoirs, but can be expensive.

If you want to, you could remove the reservoir completely and directly attach the backpack to the internals of the blaster.
