Other then the visual it is pretty easy to use all the factory stuff. On my F150 I am using all factory emissions parts with the exception of two mechanical check valves from the factory tank and the factory pick up.
pressure sensor and factory charcoal canister-
McKenzie's sells reducer so you can go to the factory filler neck-
T'd the vent to go from the cell into the filler neck and the charcoal canister-
It isn't the best looking set up and I am sure it could be cleaned up with some time and its still not "legal" and would not pass a visual but I don't have a not check engine light and it all works.
Its kinda funny because it is not street legal nor would it be race legal...guess I am a fuel cell bandito!
no there not, my buddy got pulled over last weekend for his exhaust but the cop almost impounded his truck for having a fuel cell, safety harness', illegal frame and suspension mods, and no mud flaps. so now he has to put his truck back to stock or make it a non-op truck strictly for offroad
