I know there are $700 setups out there but I am wondering if there are any inexpensive models that anyone is using like the marine racor units on ebay for 30-100 or anything else in that range. What are you using and what micron levels are they? Please advise as I am looking to do something but I have a limited budget.

 

The racor set up is fine, you can also get a napa filter base and water separator.

What is your reason for wanting an extra water separator?
