Vacuum/Vent Line replacements

BMThiker · Dec 21, 2020

After 265,000 miles, I've noticed some cracking of a few of these lines. Ordered up a bunch of parts and started replacing these. Part numbers in the pics.
You have to remove the air intake/filter assembly to get here.

This one goes from the front of the air intake (between the MAF and the TB) to the passenger side valve cover.

This one goes from the driver side of the air intake to the PCV valve.

The vac lines (90999-92002 in diagram, -92003 new part#) on the top of the intake manifold are all the same diameter hose. It only comes from TEQ in precut lengths of about 18-20" and you cut to size (see cut length in mm next to part number in diagram). I've also been told that this particular hose fits more precisely than the generic vac hose you can buy at a parts store.
