1999 F350 7.3L PSD Fuel System Question
'Water In Fuel' indication. Fuel filter replaced at local Ford dealer less than two months ago when serviced at 72,000. Fuel filter housing drain valve was plugged, used pipe brush to unplug. Brush came back out of drain port covered with a 'coagulated spoogee'. Draining the filter housing did not clear warning indication. I installed a new fuel filter and restarted truck and warning still did not clear. When old/new filter was removed did not see any signs of water in fuel? Question #1: could the 'coagulated spoogee' accumulated at the bottom of the fuel filter housing cause the sensor to give a false reading (water)? Question #2: if I pull the fuel filter housing to clean the crap out is there a way to test/measure the sensor (ohm/resistance) to see if it has failed? Or just replace since I have it apart? Any help would be greatly appreceiated!
