Yellow lever attached to back of fuel filter in "V" of engine, the drain hose ends on front passenger side of block, under a heater hose, it drains about 6 to 8 ounce of fuel when drain is opened, and you want to catch the fuel in a clean jar to see if it has water. You may have to drain it a few times to get all the water out. Start engine between draining of separator, and make sure to close the drain valve after each draining. The water in fuel light should reset it's self.

How do you drain water fuel separator on a 2003 6.0L f350 and whereis it?

Their are 2 fuel filters on a 6.0L Primary which is on the driver side frame rail and the secondary in the engine compartment (next to the oil filter the small one) You can change the filters to drain the water of their is a "Block" on the side of the Primary filter. Using a Allen wrench you can remove the plug and drain the fuel. Be sure to turn key on for 20-30 sec after completing to purge the air. if it won't run or dies out after the process the air usually gets trapped in the small secondary filter in the engine bay. Loosen cap to remove air (watch-out it will be under good pressure) and retest.
