Claim 0:
1. A fuel delivery system comprising:
a storage tank containing a fuel product;
a sump;
a pump having a fuel intake inlet positioned in the sump and a fuel intake outlet positioned in the storage tank, the fuel intake inlet forming a first gap between a bottom of the storage tank and the fuel intake inlet; and
a water filtration system comprising:
a water filter positioned in the sump and configured to separate the fuel product into a filtered fuel product and a separated water product;
a filtration uptake line extending from a filtration uptake inlet in the storage tank to a filtration uptake outlet in the water filter, the filtration uptake line configured to draw a filtration flow of the fuel product into the water filter, the filtration uptake inlet forming a second gap between the bottom of the storage tank and the filtration uptake inlet, the first gap larger than the second gap, whereby contaminants settled at the bottom of the storage tank flow into the filtration uptake line before the fuel uptake line;
a fuel return passageway having a filtered fuel inlet in the water filter and a filtered fuel outlet in fluid communication with the storage tank to return the filtered fuel product to the storage tank; and
a water removal passageway in fluid communication with the water filter to drain the separated water product from the water filter.
