Hi I'm still trying to decide what pump setup to go with. I don't want a loud can opener that I can hear while the truck is running. I've read about PPE's and ith sounds good and reliable to those who have it. Does it come with everything to hook it up and also survive Ohio winters. I was thinking about TTS and I got denied on that one I'd say. I've also read on the Airdog. Some have given that a bad grade cause missing parts and different mounting bracket. Is the PPE the one I'd like? Having a 2 micron filter like the Cat, Does it restrict any flow? I'm still thinking about doing the secondary filter setup with some kind of pump. Thank's guys, Adam
