The easiest thing to do would be to pump while shooting to help maintain the pressure level.

You might be able to do something interesting by adding an air chamber and a regulator between the air chamber and the water chamber, but it'd be silly and very wasteful because when you refill the pressurized gas will be exhausted. Typical pressurized reservoir water guns have small reservoirs so you'll have to do that fairly often.

I would not recommend this because it's too much work for essentially no benefit.

air chamber? Waterchamber?
i can give you a sceme of the thing i start with is this:
Piston-->-->-->-->Resevoir-->-->-->-->-->Valve-->-->Nozzle
i asked it because the shooting time now is 3 sec. and the nozzle size is 1X.
i hoped it would be able to convert it so it at least has a bit of use.

To convert it to a conventional CPS or air pressure blaster, you'll need...

reservoir -> one-way valve -> pump -> one-way valve -> pressure chamber -> trigger valve -> nozzle

For more info, see our articles on how water guns work and the air pressure homemade.

What gun is it? And are you SURE it's pressurised reservoir? 3 seconds sounds like too short a shot time. PR guns have variable shot time, since the volume of pressurised air can vary, but they tend to be decent.

Ah right. I know the sort you mean.

To be honest I doubt it's worth doing much with. There's a saying round here, "You can't turn a tricycle into a monster truck.". There's a limit to how far mods can go.

Honestly, you'd probably be better off throwing the thing away or keeping it for parts. (unless its is capable of shooting past 30ft and the leak isn't too bad) For one, pumps and their pipe layouts on pressurized reservoir blasters are much different than on blasters whose pumps pump water instead of air. You will have to make some modifications to the pump which may not work reliably. Then, you probably need to do some cutting up of the case so you have room to stick out a pressure chamber. You'll end up buying tons of parts that could've gone to building a homemade anyway.
