I am wanting to do this mod but I would like to know what size of hose im gonna need to make it work. I would just take it off but I gotta drive to were ever i go to get the hose. Thanks

Shopping list... 3 slip-slip elbows1 slip-male thread elbow1 slip-female thread coupling2 hose clamps6" of 3/4" heater hose4-5 feet of 1/2" PVC pipe

Add that to the static page article!

I was just wanting to make the hose longer.. I dont do any off roading so the big pvc setup is an over dose for me anyways.. do you know what size the rubber hose is that comes off the vent?

I think that's 1/2" or 5/8" ID hose...

Ok thanks..

I'm on the main site looking at this mod and the pictures, I see where the 45's or 22's (whatever they are) are used, but where are the 90's used in the back to go down behind the engine between the firewall? Same with the male/female fittings?

All elbows are 90* fittings... But there is a male/female threaded coupling to allow removal of the down pipe.
