Manifold Vacuum Experiment

Thanks man! That kinda tells alot about the pink cam. I may try the blue cam as well as deburring the primary pump check valve.
if it was fine before why do you think changing cams will fix it
Id pull the the acel pump check for crud and the gasket theres and adustment there as well
all of a sudden you shoudnt need the blue cam if she was running perfect on the pink
