Currently no problem with filters.This is my fourth winter with this truck an never had this before.Yes, some time the filters get plug faster and looks black,that for sure is asphaltene but never in tank in this shape.Just checked my check valve on Davco,absolutely clean.
I feel truck starving for fuel some times.
Thanks for the replay!
