Awesome price on a brand new Racor S3202 diesel fuel Aqua-Block II spin-on type filter for separating free water at up to 99% efficiency at flow rates up to 90GPH. The bottom of the filter includes a self-venting water drain in the clear water collection bowl so you can see the separated water and large debris and know when it is time to drain.

The mounting bracket is made from lightweight and corrosion resistant cast aluminum and features a easy to use hand operated priming pump for removing air from the fuel filter and fuel lines after a filter change. 2 fuel inlet and 2 fuel outlet ports allow you to have fuel come in and out from one or both sides of the filter, giving you multiple plumbing options. 2 plugs are included if you only need 1 inlet and 1 outlet port. The fuel ports are 3/8" NPT threaded.

You can use Racor S3202 listed below and if you do not want to use the clear bowl you can use Wix 33118 21 Micron, Purolator PER96, Baldwin BF580, BF5813, Donaldson P556915 25 Micron, or Fram P1146 replacement elements.
