What type of Vaccum line to use??

i replaced mine with rubber hoses with no problems. if you need any help on where the lines run just ask

Just get some good rubber hose's and you'll be set.

Hey Shape, how you been? i have used rubber hose for replacements, and it usually works fine. i keep some copper line around (fixing pipes around the house, etc.) and use it if a tight bend is needed, etc. just a thought in case you run into something tight.
i would just go pick up a variety of rubber lines (i try to keep a bunch of all sizes fuel, vac, windshield wiper line, etc around). i like using fuel line when possible (the duct tape of rubber lines, IMHO. LOL) as it is thick and resistant to stuff and doesnt kink too easily.

for vac routing, hope this helps (courtesy of TMoss)

also, remember they sell plastic elbows for tight bends. the rubber hoses work for me. I did use one 90 degree elbow. on mine.
