Can anyone identify this greenish goo and grit contamination that keeps coming back and blocking my high pressure fuel pump screens? It occurs on both engines so I am thinking it is a problem with the fuel itself. I have tried stabil blue and 360, and even a biocide as additives, but it keeps coming back. I change fuel filters regularly. The inside of my single fuel tank looks clean. I also have a white jelly in the vapor reservoir after the boat has sat for a few months. I am getting tired of cleaning out the screen every few hours of operation. Perhaps I hook up a portable fuel polishing system, but the parts of the tank I can see are clean. Maybe a different additive? I switched from fuel with ethanol, to valvetec fuel, but no improvement. Thanks! Seattle area freshwater 4winns owner
