On Nov 08 I got a Hydro Blitz. On late Jan this year it was not building pressure. I opened it just to learn that the pump system went dead.
I had a Tiger Shark since early Dec 08. I took the pressure chamber from the Hydro Blitz and replaced the one on the Tiger Shark.
Took me about 2 days looking for parts around the house and performing the mod. Now the pressure chamber hangs from a side, kinda resembling a shock rifle or something. Power, range, shot time and usable water have notably improved, so has pump times, force required to pump and weight gone up, not to mention now is off balance and difficult to carry it on the right hand.
I was unable to connect it from the top opening of the pressure chamber as the water tank would not let it fit, nor the parts I was able to find and use. So I place it as you see on the pics and the other way around, thought it was better the way it looks now. I could have place it in a way it would go upwards but then it would block your view or hit your face. What I basically did was to use an orange garden hose splitter which has a tight fit with the gun opening, but was quite loose on the pressure chambers opening. So I used some thick rubber rings and vaseline on both ends. Afterward I sealed the unused ends on both, the splitter and the pressure chamber, and used some straps to hold everything together. It definitely works as it is, and has no leaks at all since first assembly, but also hurts the eyes, needs some sort of extreme make over.
This is a basic table showing Before/Now specs (Largest nozzle only for now):
Level - 45 Degrees - Shot Time - Pumps
8M/9.5M - 9M/11.5M - 3s/4.5s - 13/30
Still haven´t tested smaller nozzles, nor current weight when full.
Considering that I have changed a 0.4L pressure chamber with a 0.9L one, plus the 1.4L water tank, you can say it is now a 2.3L water gun overall, giving about 2 full shots and a half. Recoil is also clearly felt now when using the largest nozzle.
