I need some help identifying this vacuum hose. I just bought my jeep about two weeks ago and noticed the hose was disconnected. I've tried to ID it using diagrams and other sources with no luck. I did listen for a 'vacuum noise' or 'sucking' and I can hear air being pulled in. I sealed for the time being with a screw and some electrical tape to keep to pressure in the line. Thank you for your help in advance.
I can't see exactly, but on that side, I would guess it's the one that connects to the inside for the HVAC, or perhaps under the battery tray area for the vacuum reservoir. Do your HVAC controls work, especially the ones that direct airflow?
Thank you for the response. I double checked the HVAC system and everything seems to be good there. I looked under the battery shelf and found a hose that appears to be a draining tube for condensation from the ac unit (not really sure). I'll attach a picture of said hose. Thank you again.
Thank you for the post. Just so I'm understanding you fully, my loose vacuum hose should be attached to the L shaped tube under the battery shelf. At least that's what I'm assuming from the pictures. Any idea what this hose/tube is for exactly? I'm just curious only because this is my first jeep and I'm trying to learn as much as I can. Thank you for your time and post(s).
No, not below the battery. The vacuum check valve(in the first 2 pics I sent) is just below the two aluminium a/c lines. It's hard to get a good picture because it connects to the bottom side of the check valve.
Should just push on unless the check valve or the hose itself is damaged. Also, for reference, that other picture you sent was indeed the A/C drain line. Apparently not all years had the vacuum canister either; not sure what "feature" needs it, but mine has one, LOL.
Ok, I'm sorry for the confusion, it's a lot easier to see in the daytime. The tube does connect to the vacuum check valve(at the "T" below the a/c lines) but the piece that you are holding in your hand in the first pic you sent connects to a vacuum canister behind the passenger front wheel. This pic is looking at it from underneath the Jeep.
