Prime the fuel filter

Hi Guys,
I changed my fuel filter on my 99 Jetta this morning, primed it, but did not fill the filter all the way to the top with diesel (I run out of "standalone" diesel), now, it gives lots of smoke, and I can see foams in the clear fule line from the filter to the pump.

I have run the engine for about 5 minutes, hoping the air will be pumped out somehow, but I still have lots of air in the line.

Do I need to prime the filter all the way to the top?

Thanks!

Oh, when I say "fill the filter" I mean: I toke a jar of diesel and pour it in to the filter through the big hole (where the valve is connected), using a funnel, since I don't have any vancum sucking device.

Siphon'ed some diesel from the tank, vegetable oil must taste better.

Fill up the filter with diesel all the way to the top, and it seems the bubbles and foams are gone, I still got some black smoke, I guess it is probably related to my advancing the pump yesterday.

If it will not purge on its own by driving - then you may need to bleed the injectors. Do a search over in 101 about fuel filters.

__. My experience is limited (both of my cars and MzLauraLee's waggin have the CAT filter kit so we run 60-80K per filter) in that I've hardly ever changed a filter but I've seen a little rough running for a few seconds after a change. They do a real good job of self-purging. Is there a highway that you can go on a 10-mile drive (10 miles out and 10 back)? If you're still having trouble after that, you've got a problem to find -- may or may not be a filter related problem.

__. Driving moves *much* more fuel (and purges much more air) in 5-10 minutes than idling.
