I have installed the CPP kit (400box) on my 59 with the original pump from the chevy. I spent hours with and with-out vacuum to bleed the system and seem to have all air out. sys still doesn't work, acts like no power at all. Is this pump powerful enough to runs the box or is pressure too low. I haven't found a pressure requirement for the 400 box anywhere. suggestions?
