I know a lot of you guys who pump use homemade pumps made from syringes. What size do you use? I tried using one of the 3cc ones I got for my injections, but it's much too small - only the head fits, and it's really really tight even flaccid.
I use a 50cc one, works fine.
In the other thread about pumping it was recommended that you use one thats about 50/60cc.
