jeez what a mess(fuel filters)

[nickw226]

I just changed my fuel filters on my new to me 08 6.4L. The engine filter was easy but changing the frame rail filter created a mess of diesel fuel all over my driveway. When I unscrewed the filter housing diesel just kept draining out until I got the new filter in. Just a couple of questions. Is there a check valve in the housing that stops flow when changing filters? when I changed the engine filter there was black specs at the bottom of the aluminum housing where the filter sits, is that normal? First time poster by the way. Great forums.

best to change them when you have 1/4 or less of diesel in the tank. also unscrew the top filter by the engine to release the pressure before getting the bottom off. get a cup or something and open the drain valve on the water separator to release some diesel.

ok, yeah i had about 3/4 of a tank of fuel. I drained about a 1/2 gallon out of the separator first, then the engine filter, and then rail filter. Still poured fuel. Must have been the fuel level.
