FC quit running

[pattypape]

Jay.
I think you are now beyond my knowledge, maybe the experts will
check in after their 4th July party.
The low fuel in the primary filter should be a clue. Great idea to
clean out the Racor. About a week or two ago there was a thread on
blowing out the fuel lines toward the tank and then forward to the
primary filter with air forced into the racor fuel lines when
disconnected.
Then, I guess it is onto the injectors, Bleed those injectors, until
the fuel runs clear. I can easily reach five of them, and the Cat
always starts.
