My XP 270 (Twin pack, more recent model) leaks from the bottom of the gun when it is pumped.
Obviously, the problem is a leak, but my best bet is something wrong with either the inside tubing or the fitting of either the reservoir or the pressure chamber.
Whenever it is pumped, water leaks, or rather FLOODS out of the bottom of the gun. If I try to shoot it while pumping, it goes 3-5 feet, which means water is being lost between the reservoir and the pressure chamber. I am just noticing this damage once summer has started.
The gun is about a year or two old.
I will post a picture when I get a chance.

This is the gun I have. The black one works fine, it is the silver one that doesn't. Looking at the picture, the leak is between the pump and the trigger loop(the thing that covers the trigger)

UPDATE:
I managed to open the gun fully. The problem is with the piping between the reservoir and the pressure chamber, which is where the pump operates. Under pressure, it leaks. I'm looking for something which will give a good seal. I have tried smaller amounts of two types of tapes and neither have worked that well. If anyone has any experience with sealing these sorts of leaks, please give me advice

Welcome to the forums, and I hope you get your problem solved!

Exactly where does it leak? There may very well be a pinhole or something. If that's the case, a bit of epoxy should do the trick.

I found the leak, but in fixing it, discovered another problem with the pump that is not fixable.
However, I would like to know what mods are possible with the XP 270, as maybe I can use it as a practice or a "junkyard" for modding other guns.
Could you tell me that?

Check the main site's review of said gun. At the bottom, there's a list of possible mods. Don't limit yourself to them, though. Be creative.

Will a CVF on a gun like the aforementioned Xp-270 really increase performance noticeably?

I wouldn't suggest doing a "check valve freeze" to any air pressure water guns. You won't get too much of a performance increase. You will be able to get perhaps one or two more pumps in depending on how big the PC is and that might turn into a noticeable range or output increase. What you will get though is a much higher chance of failure. The system wasn't designed to take additional pressure.

I only will suggest removal of the pressure relief valve if it is completely necessary for your water gun to perform better (or you don't mind having a plastic crack). That means this modification is best used only for repairs (yes, it can be a repair in some cases), and high performance modifications.
