| I was wondering if I could put a guage on my 2250xt to tell how much co2 I have left in the gun? I was thinking of drilling and tapping a hole in the neck on the gun before it gets to the co2 cylinder? it would be a costly mistake though |

| IIRC CO2 has a constant pressure as long as there is liquid still on the container. I think CO2 tanks are filled by weight not pressure. WHen I worked in the HVAC field, all of our tanks were filled by weight. pressure was dependent on temperature. |

Correct. The CO2 liquid "boils" (turns into a gas) in the enclosed space until the gas reaches its vapor pressure, and that will be the same for each shot. When all the liquid is boiled off, then you're running on the compressed gas that is left. That could be enough for many shots, or just a couple - depending on the volume in the system (valve body+empty CO2 ampule). A pressure gauge would therefore only tell you when you've nearly reached the end. A manometer would, however, be useful if you have a really large reservoir that gives you a lot of shots after the liquid runs out.
Did I get that right, Joe? |

| Sounds right to me. Slavia said it all. |

Two problems with your suggested position for the guage, even if there was any point to having one....
1. The 2250 tube is NOT pressurized if you are running powerlets.... only the powerlet and the valve have any pressure in them....
2. The tube is much too thin a wall to drill and tap 1/8" NPT for a guage (the normal threads)....
Otherwise, Slavia's comments are right on the mark....
