So I noticed I was only getting about half boost at the track this weekend and have traced it down to where the F-Hose connects to the aluminum intake (see below) - when I try to pressurize the system it comes directly out of that hole connected to F hose.

Since I just had the diverters out I am guessing one of the check valves is bad? Any other ideas? Thinking #45 and #21 in the diagram
Thanks
