Brand: Fuel Safe Fuel Cells
This synthetic "sock" filter is rated for filtering down to 31 microns.  The Vertical style is designed to work with a pickup hose oriented nearly vertical from the fill plate to the floor of the fuel cell.  The barbed fitting on the top fits into your 1/2" ID rubber hose (sold separately).  
If your pickup hose is long enough to lie on the floor of the fuel cell, we also offer a Horizontal Fuel Pickup Sock Filter for 1/2" ID Hose, Part No. FS FS12.
