Slow Air Leak Hi/Lo Range Selector

Hey guys, hoping I can get some insight from you experienced O/O. My truck is a 96 International 9400 with N14/Eaton 10spd.

Today I pulled the dog house/floor pan and found the air leak that I've been hearing. The leak is coming from the one of the Hi/Lo Range selector lines where its fits into its o-ring and fitting. The fitting is screwed in tight to the K3245 air module.

When you wiggle the air line the leak somewhat goes away and comes right back when you take tension off the air line.

The truck runs and drives fine, no issue with shifting or range selection.

Is this just as simple as swapping the o-ring and/or fitting? Is this a good time to go ahead and replace the Hi/Lo shifter lines completely for good measure.

This is a picture of what I found.

 

So pull line from fitting, cut off end, push back into fitting and see if that does the trick. Ill grab a pack of orings in the am and try this.

 

Thank you sir.

 

New lines and fittings total of $20 bucks. Thanks for the input guys.
