Black fuel filter

Black fuel filter
My filter gets covered in a black substance within a few miles of being changed. Very black and coats the entire filter. I yanked the tank just to check for any contamination but only found that the semi-clear return tube was also black on the inside of the tube. I replaced injectors 5 and 6 about 2 months ago when I popped a head gasket. The truck used to push 55lbs of boost now maybe 35.

I can back blow the filter and the fuel is black and should not be. I causes the truck to stumble before it launches. Almost like turbo lag. But there is no turbo lag with the twin set up. If I moderately accelerate at mid torque range the truck stumbles then springs to life. I am parking it and saving up for some 90HP injectors. Gotta be an injector problem.
