Hi Everyone! I attached photos. I believe these two aspects of my vacuum line are damaged. But I don't know what these parts are called to replace them? I know one of them is a check valve but when I look to replace that it doesn't have the black rubber cover that is cracked. Any help would be appreciated. Thank you so much.

The fitting here has that crack down the side.


the bottom of this has that crack... this is a check valve right?

 

The first one is the vacuum assist for the brake booster. The fitting is a check valve. The rubber thingy is a grommet. You should be able to find just about anywhere.

The 2nd one is also a check valve for your HVAC system. Assuming the check valve is OK, you only need a short piece of hose. Note the hose is larger at one end (manifold side).

If you share the year of your XJ, I'm sure someone will post part numbers. You can also check out rockauto.com

 

Part number is J3208510 grommet. Looks to be the same from 1984 to 2001, and used across a whole bunch of vehicles. I'd bet the local parts store has a generic replacement in stock. Is it actually leaking though? If you let the vehicle sit, do you still have some power assist on the brakes before you start the engine again?

On the second, yeah a new piece of hose should do the trick. Pull it off and walk into the parts store. Probably charge you a few bucks to cut a piece off the bulk hose reel.

 

I can't seem to figure out the type of hose specifically for my 1994 jeep cherokee sport. It looks kinda like this: Dorman PCV Valve Hose 47128, but this only fits 1997 and up. It doesn't give suggestions for a similar part that would fit mine. Any thoughts?
