I finally got the 1-2 accum piston out after finally finding a decent set of pliers, but now of course, another problem. I can't seem to get the 1-2 piston back in to the VB. I've searced and noticed that a lot of people used Jacks to put it back in. How exactly do I use the jack? Do I need any other pieces for height? What do I use to press against the bottom of the piston setup? Does the piston go in gradually or all at one? Thanks.
