Hey everyone I installed a hydroboost kit from CPP about a month ago and I am having a problem. First let me tell you about my setup

1967 Chevrolet C10 with a 454
Mach Performance Serp. Kit with GM Type II p/s pump Remote resrvoir (with vent).
Factory p/s box

I have all the lines setup according to the instructions.

When i first put it on it had a lot of peddle kickback after bleeding a lot the peddle kick back went away. now the hydroboost unit whines like crazy. It starts off quite then gets louder. its almost unbearable it sounds similar to a supercharger whine but louder. I know its the hydroboost becaused i open the hood and the thing is screaming. also when i shurt the truck off the fluid level raises to the point of overflowing. Its really starting to annoy me. CAn anyone help me out
