Where do you mount this thing? I was thinking either under the battery, or between the windshield washer and coolant resovoirs. Also, how do you route the hoses? It looks like one hose should go from the metal tube on the UIM to the separator and the other tube from the separator to the pcv valve. Lastly, which hose goes to the top of the separator and which hose goes to the bottom of the separator? Thanks.
