Review on Ideal Fuel Water Separator Marine 120AT NPT ZG1/4-19 Automotive Parts with Fitting - Complete Combo Filter Diesel Engine (Includes 2 Fittings, 2 Plugs) by Julian Davidson

Great little water separator and filter. Yes, the image is upside down in the ad. (Apparently the seller has no idea that fuel floats on water). Important things to know. This filter has four ports, two inputs and two outputs. It comes with plugs for two extra connections (which most people don't need) BUT the plugs are not teflon taped and screw tight. If you install this filter and do NOT remove these plugs, cover them with teflon tape and put them back in place, these plugs will likely leak. (It's really easy, by the way). If you don't do this, you will be convinced that the filter is leaking because of the filter element itself and you will be disappointed.
