ok, canister has been deleted, but i'm still getting the vacuum.  hoses were done with a y fitting, and m6 bolts are in the engine.  anyone else have an idea of what it could be?

dealer tested that the hoses can be blown through, the breather hose ends now right around the tank, pretty far from the engine heat, and the fuel overflow hose is still going through the stock routing...  could it possible be the gas cap?  no idea what else it could be now and i've pulled it off and i dont see any issues with it.  do you know how i could test to see if that's clogged?

i guess i should mention that the tank has been caswell'ed but the way the new monster tanks are, there are no hoses inside the tank, and everything was removed from it prior to coating.

have them swap out the whole gas cap area and see if you get it still.

Is the breather hose T'd into the overflow tube?

yup, and was done by the dealer, not me.

i think i'm just going to go and pull off the gas cap and blow air through where the hoses connect to it.  if that's not clogged i'm just going to call it a day
