I got mine done at a proshop. The guy took off the valve than placed a filter with a long tube bent 90 degrees at the end into the tank, than he put the valve back on and screwed it in. The tube is bent up, making it much harder for liquid co2 to enter the tube cause all the liquid is at the bottom of the gun. It only costed my $15 to get mine installed. Oh, that's $15 Canadian.
