I recently did the Bravada shaft upgrade on my 2000 ZR2. After removing the actuator I wanted to remove the vacuum hose. I traced everything back to the vacuum accumulator, transfer case switch and Tees. Can I remove all the hoses except for the line going to the HVAC? I want to clean up the mess of hoses going back to the t case and cap them off at the switch and make a new vent for the T case.

 

You can remove them. I wouldn't recommend leaving the vacuum source line attached as this can lead to problems if the switch decides to start leaking; t-case fluid in the vac system is a PAIN to clean out. But the one that runs up to the actuator under the battery can definitely go. The other is just a vent and can be left without concern.

 

Thanks. I decided to remove them all. I ran a new T case breather line, the vacuum switch I cut and plugged the 3 nipples with silicone then cut and plugged the vacuum lines next to the fender right off of the main supply line after the T connection. I even eliminated the vacuum chamber since the hose keeps falling off.
