Holy No-pumping-awesomeness, Batman!

I'm drooling. Want to know why? Because after seeing the water gun conversion thread, I remembered I had this:
An automatic, no pumping, battery-powered water gun. If I was to convert this into a Nerf gun, imagine the possibilities!
Since I don't do much Nerf related any more, anyone have any ideas how to go about doing this?

Also, Super Soakers work just like Nerf guns do (air pressure ones at least). Because it takes so much pressure to pressurize water, only pressurized air is used on air pressure water guns. CPS water guns typically use rubber, a different system.
I don't think that modifying this likely weak water gun will be worth the effort. Try modifying it, but do not expect good results.

Obviously, Doom, you don't know your pumps. That is hydraulic only. It could be used with air, but sucks. I know this by both experience and learning. They use the same thing in busses for hydraulic applications with steering and in construction equipment to generate oil pressure to move hydraulic rams, unless the pump is like the one described below.
It it a motor with a paddle on it. The water from the tank goes into surgical type tubing which is forced through a nozzle by the paddle.
Hey Dan, does the water ever come in contact with the paddles? If it doesn't, then it won't work with air. It would be the same type of pump used for medical use of moving blood during open heart surgery. If it could pressurize air, Doom, you could see the problem it would create. I am not trying to pick a fight here, I'm just trying to spread knowledge.
To solve this dilemma, however, one would just have to listen to 3nerfiteers and put their hand in front of the gun to feel for air. A vane pump would supply a bit of pressure, but not a significant amount. If it were a peristaltic (I now remember its name) pump (medical use pump), air would not be forced to compress as there is an easy way to travel around the lumps in the flexible tubing.
Anyway, the reason why it is believed water takes more force to achieve higher pressures than say air is because of the difference in atomic energy during normal states of matter. Liquid water though, has more fluid friction than air (duh) so different techniques can be used for water but not air. To go back to the atomic energy for a minute, since water does not want to move as readily as air, a force upon water can be greater than a force upon air, depending on that force however. A gear pump (hydraulic) relies on water's tendancy to stick together in order to generate pressure. A pressure sprayer uses several piston pumps designed for high pressure water. It resembles an automobile engine. The pump can generate incredibly high water pressures, but since the seals are not perfect (and a gas takes the shape of the container its in), very little air pressure can be generated with them.
I was kinda skipping around when I was typing this, so if anyone finds an incomplete thought in a paragraph or sentence, please tell me so I can fix it.

Or you could do the same thing, but just use it to replace the pump. Have a separate trigger to activate it so it would pump while you ran around, then you could fire full auto. I think you have a valuable resource there.
Also, what GeneralPrimevil was saying is basically that air compresses more than water, so it takes more force to create good pressure. This thing should be able to move water well, just not fast. Imagine being in a low gear on a car; slow but strong.

I converted a Max D last year, you can reduce the pumping pretty simply.
Well, in the past few weeks i've finnally gotten around to modding my max D 2000 supersoaker. Basically all i did was do a barrel replacement with about 6 inches of brass. It had fair range, but alot of pumps.
See my write up here
It is a little confusing but here is a revised way to do it. (sorry no pics, I have no digital camera.)
1) Do a barrel replacement, cut the nozzel off the snapping ball valve.
2) Remove the plastic water tank and pull out plug on the bottom that comes from the pump.
3) Cut a piece of 1/2" PVC to fit over the Vinal tube that attaches to the ball valve with enough space that the plug that you pulled out of water tank will fit too.
4) Sand down the inside of the PVC and outside of the plug so that the plug will fit into it snugly.
5) Goop the PVC over the Vinal on the valve, cut the tubing from the pump to the plug (it is not long enough to reach) and goop the plug into the PVC
6) Cut the plastic on the back of the pump so that it is pointing straight back instead of forward
7) Splice the tubing from the pump to the plug with some lager diameter vinal tubing to reach to the back of the PVC/Large diameter tubing, and drilling a hole at the back of the casing where the pump ends so that the tubing can be routed ouside the gun to the plug.
8) wait a couple days for you goop to dry and enjoy.
