Vacuum lines are Broken
Good afternoon gentlemen,
I was working the looms and such while my engine's out and noticed that the vacuum lines that are attached to the RH aft Intake manifold which feed into the TPI EGR I do believe have been so dry-rotted that they have broken. Does anybody know of source to purchase pre-bent, Genuine GM Lines to replace them. I have raw vacuum lines, and elbows and such, but am worried about maintaining proper vacuum if I clutter the new line with 90 degree fittings that you can buy at O'Reilly's.

Buy the rolls of hard plastic vacuum line. Lightly heat the plastic line and you can form it to whatever shape you like. Just don't overheat it, start small like a hair dryer, and work up to hotter as needed.
