Water in Fuel warning light... how to drain?

Hi guys. I haven't posted in ages, but I'm finally able to get the bus back on the road and ran into a "Water in Fuel" light on the dash.

Does anyone have a photo or description of where the water drain is on a 1995 Genesis short bus? I'm ready to get this puppy back on the road and don't want to blow it up before I get out of the neighborhood.

there should be a fuel filter next to the engine with a peacock on the bottom. drain it, turn the key on for a few seconds shut back off and then close the peacock.

They aren't all alike and may have been added after the sale. It will probably look like one of these. Probably in the engine compartment.

Like superdave said there should be a petcock on the bottom. If it is the kind with a glass bowl, simply drain until the water is out. (it will be a different color, you can tell)

i've drained a few of these separators, and if you are on concrete, its messy and you'll smell like diesel until your next shower. you might try using bottle or something to catch the water.

fwiw

The standard filter is on the engine but it may have a separate fuel/water separator as well. Trace your fuel lines back to the tank to see what else might be there. Any such filter will have a simple petcock/drain on bottom. Definitely have a pan or bucket handy...it is a messy task.

dont drain too much or you may lose main pump prime if you are mechanical with a suction type fuel system..

any idea those here or may know, what triggers that light to come on?

I believe most of the "E" engines have a simple detector on the filter.

Water

Ok, can something be done about the need to post a bunch of unnecessary words?

Most I've seen have a float in the primary filter/water separator that will float with water but not fuel. There also should be some sort of petcock on the bottom of it to allow it to drain. The filter is usually under the bus on or near a frame rail.

Thank you to everyone who answered. Using the 'trace the fuel line method', I was able to find the filter (I never would have guessed it would come out of the TOP of the tank instead of the side or bottom ). Drained some fluid from it, but it was next to impossible to see any differentiation in color from my position under the bus, so I had to guess when to stop. How much water is necessary to make the water light go off? How much fluid is "too much" and puts me in danger of losing the pump prime?
