Fits Jeep 4.0 engine
It works for saving the OE plastic line and replacing the old rubber. The intake port side fought me a bit, the original setup has the plastic line going quite far into the rubber/intake manifold, the rib in the plastic line was halfway into the rubber on my original line, so I wanted to get it as far in there again, took some lubrication and wiggling but it eventually went in.

These hoses fit perfectly
I've had these on my Jeep TJ for over a month now. I had no idea how bad the old ones were until I replaced them. They fit perfectly and there are are no leaks. Along with these hoses and the new valves, I have noticed a increase in power and fuel efficiency. They're kind of expensive for a couple of short hoses, but they're hard to find and no one was beating the price on Amazon.

Perfect replacement for the CCV elbow hose in the rear of the crankcase to intake manifold on jeep 4.0 I6
If you are trying to find the hose replacement for that stubborn rear CCV (PCV) valve line on that 4.0 I6 jeep that you have to break off from replacing the grommet look no further. This is the replacement hose kit for the CCV valve in the rear of the 4.0 I6 jeep motor. The only CCV that comes out will be next to impossible to remove the old hose without it falling apart from age. The smaller hose is for the intake manifold connection to replace as well and I highly advise you do that one as well. The plastic hose fitting that go in between the two be careful not to break those pulling the old hose off. But, this is a fine replacement and is a big saver on cash over the dealer to fix up the rear CCV hose line connection from the intake manifold to the CCV on the crankcase cover for that rear connection to the CCV elbow (its the grey one in the back).

Exact fit
Just needed the two end pieces for the crankcase tube for my 2001 wrangler due to the other ones ripping when I had to remove the tube. These are an exact replacement

Save over $100 by just replacing the cracked rubber!
A little tough fitting to he rubber over the OEM tube. A little heat helped. Perfect replacement for a fraction of a full replacement!

Will split in a month
Used to be a good brand the quality of the rubber they use has gone down you can tell china been cutting Conner's. The rubber will split off the hose after a month on my 97zj your better off using fuel line rubber than paying for this over price poor quality hose.
