I need abit of helping fixing my airtech. I modded it with a crayola barrel and plugged the bits on the pump that lets extra air out. I am going to put pvcp on it but i haven't gotten to that yet. Anyways, when I pump my airtech up the air leaks from the pumping bit. I wasn't sure what might fix this problem, so i wanted to know if anyone else had this problem or might have had a similar one? Thanks in advanced.
