Need help with extended differential vent hoses

I heard that you shouldn't wade into water deeper than your hubs unless you extended your differential vent tubes. Since I have a mostly stock '95 YJ Rio Grande, I figured I'd probably want to extend them in case I ever decide to go swimming. After looking around my pumpkins I noticed that there was already a hose coming out from them. Since it's stock and I've never seen a differential vent host, I'm wondering if this is an already extended hose or something else.
Here are some pictures:


The hose comes out of the top right side of the front diff pumpkin and snakes around to near the radiator on the drivers side. It's the gray/white looking cap in the second picture (a little hard to recognize).
Is this standard for the '95 Rio Grande's or did the previous owner put them in? There is a similar one in the rear but I couldn't quite figure out where it went. Thanks.

Those are factory diff vent hoses, and will do just fine on a stock rig.

You can still suck water into your diff's .. very easy if you have leaky seals .. rule of thumb .. change the seals every two years for protection .. or whenever you see leaks happening (which ever comes first).

Change your diff fluid after every major dunking in the water (80 - 90 weight gear oil is recommended) to keep things clean. I just changed the diff fluids in my buddies axles yesterday .. they were dunked and the water in there was killer! The juice plopped out like chunky stew .. and there was some rusting already starting on the diff cover.

We cleaned the rust off using WD-40 and a wire brush attached to a drill.
