What is the average pressure inside of a C02 tank?, i want to know because i am buying a drop forward (http://www.actionvillage.com/is-bin/INTERSHOP.enfinity/eCS/Store/en/-/USD/DisplayProductInformation-Start;sid=WuCcE_p7CCqcm70MhTRcu_Dd5U_lGnvKWTU=?Pro ductID=hOesFAY78dYAAAD3cWulA_2t) (please post any opinions on this item) and it says it has two holes, so i was going to also buy a gauge, but i want to know the pressure in the co2 tank before i make my choice. as of right now i am thinking of a dye gauge (http://www.actionvillage.com/is-bin/INTERSHOP.enfinity/eCS/Store/en/-/USD/DisplayProductInformation-Start;sid=WuCcE_p7CCqcm70MhTRcu_Dd5U_lGnvKWTU=?Pro ductID=K0ysFAY7WTMAAAD33nilA_2t)

will this combo work? any thoughts on what i should do, please tell me
thanks

the psi on a C02 tank is roughly 800psi. So the gauge is too high.

Here is the right one:

That should show you a few things!

Funny a minute ago it was given me a forbidden.

on that site it said some guns work better with a siphon tube (takes only liquid into the gun), and some with an ANTI siphon tube, iv never heard of a siphon tube, what kind of gun would work with that?

am i the only one that finds that graph a little confusing, why do the lines from 80* to 0* go straight across?

The oldschool tippies ran well on siphoned CO2. Siphon is the opposite of anti-siphon, it sucks liquid co2 into the gun...

yea but u dont want liquid co2 going into ur gun u lose alot of pressure just like when ur tank gets cold ur pressure drops

Blowbacks and pumps can run liquid/easily be adapted to run liquid. Any gun that requires a reg cant run on liquid and some guns that dont require a reg wont run liquid either.

Liquid co2 doesnt make you lose pressure the idea is instead of using the valve to meter out a small amount of unstable co2 gas to propel the ball use the valve to meter a small amount of liquid that will flash to gas and propel the ball. liquid co2 will work well below 0 where even 40* weather will give gas issues. co2 is self regulating but it gets cold when it turn from liquid to gas and causes drop off, running on liquid will not give this problem. Its hard to explain and there isnt much information on it anymore because HPA and EP guns are so popular now.

Here's why..........CO2 liquid can only expand into a gas if there is room to expand into a gas. The liquid shares space with the CO2 gas. So basically if your tank is 80% filled or 20% filled.......there is still the exact same amount of pressure output! Hence why the fill guy can't throw a guage on and tell you how full your tank is. The only way to tell is to get a dead empty weight and engrave the brass valve. Then you could take your tank up and ask for a weight so you know how many ounces are left! As far as temperatures go.....in the winter at 32 degrees F. I am lucky to get 400 PSI which is almost exactly what the chart shows. In the summer if you left your tanks in the sun on a 100 deg. F. day they will hit well over 1800 PSI and that's when you typically see burst valves blowing up! I typically won't give out completely full fills at that temperature. However you'll notice that in the cold winter........you could fill your tanks up higher than 100%.......I still won't recommend it.............but.........I might have done it once or twice during pump tournies!

On a side note.......you will severely increase the tank temp in the winter with your hand on it. Just hope it doesn't get really cold from playing and your hands get sweaty at the same time :)
