Well, as you know, an Autocoker is a pump gun with pnuematics to cycle the pump arm cocking the gun and chambering a ball.
Instalation is as simple as unbolting your front block and screwing the pump on. Going back to semi, you'll have to retime your 'gun, ut that shouldn't be a problem.
They sell for about $20, But CCM makes some really cool ones with huge price tags ...
