Mark--The next time you need to clean the sediment bowl, the easiest method is to use a pressurized can of WD-40 with the long plastic straw attached. With the filter element removed from the filter canister, the WD-40 straw can be inserted through the vanes of the vortex generator. A few blasts of the WD-40 at several different positions will dislodge the debris that will collect at the bottom of the bowl. A splash of diesel will wash it out nicely. It may take a few "cycles" to completely clean the bowl but the process does work quite nicely. On our boat I have a plastic tube connected the the "drain" spout on the underside of the sediment bowl. By connecting this to a small bronze hand pump I am easily able to suction out the debris in the sediment bowl. The small amount of WD-40 that remains in the bowl easily mixes with the fuel and creates no problems.
FWIW...
