CPS 3000 backpack replacement!!
I just picked up a CPS 3000 from my cousin (the same one with the CPS 2000), but it was missing the backpack. Does anyone have any ideas on how I could possibly make my own, so that I can use the CPS 3000?

A backpack modification with the correct hose coupler is what you need: http://www.sscentral.org/tech/mods/backpack.php
joanna knows the type of hose coupler to get, so wait for her response for more information. The homemade backpack itself is a soft pack much like the CPS 3000's. If you want a hard backpack, you can make one from PVC or ABS pipe. You also can make one from bottles or other water containers. Really easy.

Ok (steals images from my older thread).
You want to look for a "male" hose connector like so:
You'll need to find a way to attach this to your 3000 -(it fits well in a 3200, but the hose/gun connection is different to a 3000) - it may be easy.
However, if you find no easy way - you can improvise as such:
By cutting the pipe work back and filing it smooth - you can cut the connector down, and you can superglue the two faces together well. You might experience problems here - the "male" connector I used was "longer" than it needed to be, so there was spare space for the casing in between the "male" and "female" parts.
Your connection from the back pack should be one of these ^. The hose is a basic garden hose. That stuff is the cheapest stuff possible, but it still holds 100 psi easy - but you don't need pressure resistance for a feed to the pump.
And you'll need to find your own way of attaching the hose to your improv backpack - you can "ask the audience" though.

I'll be "the audience" for now...
The backpack mod article asks you to just cut a hole in a bottle cap and stick the tubing inside--simple enough, but with some leaking. I decided to go way beyond that, so I created a heavy-duty system. I just used actual PVC fittings; a 1/2" hose barb, a 2"-to-1/2" threaded bushing, and a 2" male adapter to clamp the trashbag to the bushing.
And by doing that, I discovered that...it's completely pointless. Using PVC just increases the price and makes things way too heavy, and the "sharper" threads cut the bag in places--but since so much of the bag was clamped anyway, at least the seal held. My suggestion is to do what the article says, but use epoxy to hold the tubing onto the cap and create a seal that way. Also, no matter what you do, get lots of tubing so you can put the bag upside-down inside the backpack; this makes sure no air gets pumped until the end, and siphoning makes sure the water gets to the soaker.

I wouldn't know where to look for the connectors on that side of the Atlantic, but I understand that they are fairly universal.
Good luck on that.

These connectors are very common, usually found in the garden hose sections of larger home improvement/DIY stores such as Lowes or The Home Depot. Lowes has an excellent selection and it's found near the PVC, and I'd imagine it to be similar at The Home Depot.
They have both metal and plastic pieces of this type. Normally, I'd use metal, but my backpack and compact APH have plastic fittings and those would be easier to cut if you're doing something like what joannaardway did to her Triple Aggressor. Of course, they might even have ready-made one-sided pieces, but I wouldn't really know.

Sorry about bringing up a really dead topic I started, but...
I found a nice backpack- Around 3L capacity, with room for other gear/guns. It has a small camel pack like thing, but works better, because it keeps the water above where you would normally pump the gun, so it will keep a steady flow to the gun. Here is the link to the backpack- It claims that it is 35L capacity, but that is the main bag, not the water pouch. Below is an image of the bag from the website:
This bag even has a cover so that the contents of your bag don't get wet. However, it covers the bag, making it take longer to refill. But hey- If you're in a water war, and you store guns in it, it will be wet anyways. I am going to modify the connector for the camel pack to fit in the CPS3K slot for the backpack. I might expand some holes so that I can twist and lock it in the slot

Nice find. But unless you're using the main compartment for something else, shouldn't you just use a camel pack? Besides, 3 liters isn't all that much for a backpack...
At any rate, a camel pack reservoir would probably be completely leak-free, so good luck with the mod! Also, it would be easier I suppose than just carrying the weight in your hands, like with a CPS 2700.

Monsoon is right. There is a small bag inside the backpack where you put the camel pack, and the rest would be storage. The backpack is large enough that it can almost fit my 3000 inside it, so it has great holding space. I could carry around my BBT guns in the backpack, while I carry around my 2000 and 3000, which would be around my neck

Would it weigh you down a lot, or be too bulky in the heat of a battle? These are the most important things to take into consideration when thinking of using something for a water war. There's nothing more irritating that bulky equipment when you're trying to make a run for it.

The bag, when full of water and some lower key weapon would be not too bulky... there are straps on it which can make it contract to the point that the straps cannot be pulled anymore. The straps are comfortable, which is the real thing about weight, as well as where it is on your back, but I don't think that it will be too heavy. If it is, I will just modify the pouch and make it like a camel pack
