Water Separator . . . ?

[Sailagain]

So how do you drain the fuel / water separator on a diesel? Is it as simple as opening the lnut/bolt on the bottom a couple of turns until stuff comes out? And then tighten it?

Yeah I am new to this. So don't laugh

That's pretty much it: open the petcock and drain the water out then tighten it back up again.

Ok. Engine off or on at the time?

I tap on the bowl as its draining, loosens the junk

You can drain a little while the engine runs, but it will airlock if you run too much out. Depends on your level of contamination. It is usually better to drain it off, before starting the engine and then refill the filter housing with clean fuel prior to starting. It works best if you can gravity feed the filter housing from the tank. If not then have a small jug on hand just to fill up the housing.

1. Make sure engine is off and cool to the touch.
2. Open vent plug.
3. Open drain valve to remove water.
4. Close drain valve immediately after water has emptied from filter.
