Id like to see some pix of this in the engine bay. Im guessing you sealed off the stock opening in the front of the box. How deep have you had this setup?
i will have to find some pics for you , there was a good write up on it on madxj. and go jeep i think..
i cant find the pic i want but you should get the idea here the corrogated hose clamps over the elbow and is sealed with silicone, the hose snakes under the manifold then up to the firewall . i drilled the firewall with a hole saw and used a abs flanged coupling inside the firewall i used a 22 1/2 degree elbow pointed downwards.. if any water happens to come in the grills it just falls right past the intake pipe,
this last pic kinda shows it . i had just rebuilt the motor and done an intake swap and headers the hose dose not touch the manifold now
the abs fitting i used were bout at an rv center, they are for trailer sewage they have a slightly different dia. than regular abs,, this is because the pipe i used was an exhuast hose from a gas water heater . temprature rated, it was free,,
yes the front of the air box has been sealed off,
how deep ? bout 1'' from the bottom of the windows is the deepest, no pics of that one.. got stuck in hole once, the water was pouring in the door seals,, by the time i got out i was almost knee deep inside the jeep , but it was still running fine .
