There are aftermarket vent hose caps out there. You will have to go to the junk yard to get a classic hose cap like Max showed on his truck. I see there are enclosed expansion vent caps. Pleated like an accordion that will not vent but expand to relieve pressure. I guess you could put a child's balloon over the end for that. For four wheelers that ford creeks and rivers one of those vent caps is best. Or go with the gas filter like Dave said? I'm pretty sure NAPA will have a vent cap for you.
A simple piece of window screen with a wire tie will work. Just try to tie the hose so the end of it is down to try and minimize water entry when you are driving in the rain.
I worked on a Army 6x6 once. All the gear box and diff vents were plumbed with metal tubiing and hose, and they all ran up the frame and back from the front and ended up very high mounted to a block on the firewall. That was the normal venting system, I read elsewhere that they had a kit that extended this and the air intake for the engine even higher for fording rivers and lakes.

IIRC, some military vehicles went one step further than locating the vent up high. They had a system to lightly pressurise the transmission, transfer case, and axles. When fording, you'd set a valve to the corresponding position, and the components now had a slight pressure to keep water from getting in.
Maybe somebody with motor pool experience can chime in to confirm this.
