This was a project next on my list, so I'm glad that they did it first (my filter budget is shot for the next 5 years).<br /><br />They tested and analyzed about water / fuel separator filters and the WIX 33225 did very well as did a Tempo model. These both had smaller pore size and held more water than the Merc unit.<br /><br />Pick up a copy of TBM or I think if you wait a month it may be on-line at http://www.trailerboats.com
