If you have a big engine and a serious fuel quality problem, this is the filter for you! Capable of removing a large amount of water from your fuel, this high flowing filter will do the job. It features a nifty hand pump primer to clear out air after filter changes and a convenient water drain that will accept a hose. The integrated water sensor probe will interface to most water sensing circuits. This is normally a $300 filter, but since it is the last one, and too big to fit under the hood of most pickups, we are clearing it out. These are very popular with boaters!
