Thanks guys. Henry that is what I would like to do... So just put a T on the inlet to the filter or dryer and that's it? I would like more CFM and it won't help much since the other one is tiny for things like nail guns on roofs but any little bit helps. Now the hard part is making my spray booth and all. I am thinking that it may not be worth doing this myself and painting my truck at home. I may wait until fall and when I am going to college taking auto body and just doing it there but then again I have rust comming under the old paint and it's bubbling bad and rust dripping and I don't like that. The paint on it now is like a few years old (maybe 5 or 6 I think) and it's really good shape but there are about 10 spots with bubbles, some scratches, etc.
Thanks again and anymore info or help is greatly appreciated!
