Finally changed the fuel filter on my 2003 Suburban with flex fuel.
After two trips, I got the correct replacement fuel filter (a Fram
G8219 needed for flex fuel) with a nut on the back and a slip or snap
fitting on the front.

However, when I removed the front slip fitting, 3 items fell out of the
line.  A yellow O-ring, a black plastic stepped washer, and a metal
washer.  My guess is these items should not have been loose, and should
not have fallen out.

But they did, and I cannot figure out what order to stack them back
into the fuel line end before snapping the fuel filter in.

I'd be happy to take pictures and upload; don't know how to upload with
Google groups.  I bought the Suburban new, but it now has ~50,000
miles, so no longer under warranty.  Plus, without a fuel line, it
would not be fun to tow it to a repair shop.

Does anyone know how to reassemble this thing?
