After playing around with this thing, it seems to run the best with the restrictive vacuum going thru the vapor separator connected up, and leaving off the other line that's T'ed into the pcv line. So the only other line connected to my canister is the fuel tank line.
Thanks Scotty1998 for staring up this thread. I probably wouldn't have took the time to look into all this otherwise. Plugging up this vacuum leak has sure made a big difference with my rig. Hope others have the same luck.
