A method of removing water from phase separated fuel in a fluid reservoir, said method comprising the steps of: identifying layers of fluid within the reservoir; determining the heights of the respective fluid layers within said reservoir; providing a vacuum and a first suction tube, said vacuum and said first suction tube providing a first volumetric flow rate; inserting the first suction tube into said fluid reservoir; removing a first fluid layer; replacing said first suction tube with a second suction tube, said second suction tube having a greater cross-sectional area than said first suction tube such that said vacuum and said second suction tube have a second volumetric flow rate; inserting said second suction tube into said fluid reservoir; removing a second fluid from said reservoir; and sending said second fluid through a filtration system.
