This all depends on the feedneck on the gun. That is, the circular part on top of the gun that connects the hopper to the marker. If it is clamping feedneck, simply release the clamp, push it down all the way and close the clamp appropriately. Others you may have to unscrew with an Alan key, and on the lower guns, just push it on their to the best of your ability. Though clamping feedneck is by far the best to have on a gun, due to the fact that it decreases the possibility of the hopper coming off.

A "feeder" is just another name for a hopper. The correct term is "hopper"

The dye Rotor.
Definitely a tank before a hopper. If you go on Zephyr Paintball they have a 20 oz C02 tank for only 14 dollars and a proto primo hopper for also 14 dollars.
No, all paintball hoppers have a standard neck size.
The Feedneck.
Yes. you may need a neck adapter though.
A paintball gun, unlike airsoft or real firearms will have a hopper on top, and will have a co2 tank sticking out of the back.
Hopper or Loader
Most paintball guns use an above hopper instead of magazines or clips like firearms. The standard hopper holds 200 rounds. Most magazines for paintball sim-markers are 30 rounds. No paintball guns use clips.
In California have to be 18 years or older to purchase a gun but any one can buy a hopper because it is not considered a weapon
