jaja i figured that one out im not that stupid. I meant how do you know you putting in the optimum ammount?

A gauge helps to tell the psi, and you need to calculate the amount of "fuel" needed. That will determine your meter pipe size.

that's the matter ...calculate

A little more detail and/or proper English would help.

Do you mean you have to get the fan to fit through the 2" part? Normally, the fan is installed via the cleanout plug at the gun's breech end.

What kinds of fans did you look for? Computers use two types; 3~4" muffin fans for circulating air in the case and 1~2" fans strapped to the CPU to keep it cool. Both types are brushless. The CPU fans will fit into/through a pretty small opening.

Both work fine. A larger fan is better for ventilating the chamber after a shot. A smaller fan might work better for getting a higher burn rate during firing. Both sizes of fans work well.

Are there any stores that I might be able to buy the propane tank adapter at? I'd rather not buy it online (BC-Arms).

When you're looking for a place to buy something from a store near you, ask yourself this question: will the regular customers ever have any use for what I'm trying to find? In your case, the answer is no. Unless you can find a dedicated supplier nearby, your best bet is ordering online.

As blasphemous as it may be, you might be disappointed if you order things from BCarms; I ordered a stungun FOUR WEEKS AGO, and there's been no sign of it since. If you do, get something small (like a propane tank adapter) to make sure if you do get shafted, that you're not losing large amounts of money.
