LJ70 2LT Fuel filter drain how to

[tintinmt]

Hi, 1989 LJ70. I can't find an instruction for draining water from the fuel filter. I can see what looks like a drain pipe at the bottom of the filter. What do I turn to release any water? How much to drain? Do I need to prime the fuel system afterwards?

You undo at the bottom. I would replace the filter if you don't know the history. System should self prime as far as I know.
