Removing Intake Manifol: Help identify these wires/hoses

**Genes1s** · 03-20-2019, 01:22 AM

I'm in the process of removing Intake Manifold. Removing all the bolts were pretty straight forward, but disconnecting a bunch of stuff underneath was a little tricky.

I'm down to last 3 items connecting to the IM. These 2 wires and what it looks like a vacuum hose. How do you remove these 2 wires and the vacuum hose. I gave it a good yank and it wouldn't budge...

Those aren't wires, they're rubber vacuum lines. They just pull off. They can be tricky since they've been on for so long. Also, try to pull closer to the base of where it plugs in to the intake manifold. The further down you go the more it stretches and grips the nipple it's attached to, like a chinese finger trap.

Yeah, just pull on them and they come off. It can take some effort. Plan on replacing them, they are most certainly dry rotted at this point. And a total pain to get back on with the manifold installed....

Well, I really yanked it hard this time and it came off. Learned that one 3.5mm is the vacuum supply to the fuel regulator which is hard tubing with the rubber cap, which I shredded the rubber cap, should be here in few days from ECS. The other 3.5mm vacuum line is to supply to SAP Valve. This one is intact. The biggest of the 3, is the vacuum supply to the tank vent valve for evap emission. All important stuff here! dang....so many freaken vacuum maze underneath the IM.
