i dont know your parts stores up north there. but pick up some new vac line. about 4 feet, and replace the old crap. you need 2 new Tee's as well, i got some small white tee's at advance auto here, a 2 pack for 2 bucks. vac line is a buck a foot here, or less.

if you got taped up lines they are leaking. also check the fat vac hose off the TB, it loves to crack.
