homemade snorkle question

Ive seen this done somewhere but i cant seem to find it. How can i build a homemade snorkle for my carbed 4 banger? I was thinking that i could just run the intake hose to the fender, and then fab up something with sometype of pvc pipe and so on. How do i keep the rain out?etc. Ive dedided im making my Jeep a trail rig, i bought a 4runner today that will be m dailydriver. Im so excited bc now i dont have to worry about on road performance as much. I got my 92 runner for 2500 bucks and it has 80K on it and fully loaded with 4wd. Id rather break my Jeep though. Thanks alot.

He has a good idea on diverting the intake to the rear on the firewall. It's in the tech section. I know it's not what you wanted but it is an idea that doesn't require you to cut through the fender.

I've got an ARB Safari Snorkle I'll sell you if you want. Hit me @ [email protected] for details
