If you are gonna run them things, at least run two of them at the truck and use a Y with two hoses to the tank, this way you double your filtration, which means having to clean them less, and even when they are half full of crap you still have good vacuum.
And for gawds sake, if you run a stainless insert instead of the sock, turn them around, they work in the opposit direction with the stainless insert.
And now that you have it oriented correctly, put a nylon on the stainless so you can just brush it off, since the crap will be OUTSIDE the basket.
If you want to trick it out some more, drill some 1/2" holes in the rubber bottom of the insert, the nylon will protect these, yet still allow good airflow.
If people would get away from "seeing" the dirty water, you could just get a real nice FILTER BOX at the truck, and be done with it.
EDIT: My gawd I just looked at the #of views for this thread, what makes so many take a look at a filter thread? I'm guessing it appeared as a new technology thread.
