Well, I sprayed off top of IP with brake cleaner, and then blew it off with compressed air. I did not repeat that after pulling the lock-down washers, so it's possible that there was junk on top of the o-rings that fell in, but the stuff was inside the delivery valve assembly as well.
Old o-rings were deformed but were not falling apart. I did not attempt to ID the black stuff - it was very small - doubt that I could have felt it with fingers. Only one complete tank of fuel post delivery valve rebuild, that was burned in highway driving at speeds from 65 to 90 mph over the course of 6 hours, 450 miles.

Was it grit that fell in when you opend the delivery valve? (some grit can hide on top of the o-ring seal) Was the black stuff soft and rubbery? If you have run at least a tank of fuel through the car, most of the algae that would be caught in the filter will be gone. If there is algae in the clear filter, you should be able to see it without cutting the filter open. At 11:26 AM 5/10/2006, you wrote: >Inside of pump was shiny.
