Vacuum line works but eventually came out and lost one somewhere in the desert. I'd like to find some T or Y shaped rubber body trim that would hold in place better.
Just use a tube of flex seal flex paste. Squirt it in there real good and run your finger along it to clean up the line. Just like caulking a bathtub ?
Whenever they start to bug me I dig ‘em out with a hooked steel pick, like the one in this set: https://a.co/d/7B1PDcB
Works great.
I did have some of that rubber tubing in there as a preventative for a while but it kept flopping out so I removed it. If my jeep wasn’t a dedicated trail rig I’d probably care enough to try again.
