It is good that you found it, and that it was not more serious, though air in the fuel system is bad enough. Thanks for sharing that with everyone. Your descriptions didn't exactly match a fuel aeration problem, but then again, it is difficult for anyone to give advice or know for sure what a problem can be. Makes for a lot of guessing, but even so,.. Everyone learns from it in the end, and that is what i like about this forum.

I would definitely NOT bypass the davco for very long. Fix the davco or replace it. Always use a 10-micron filter in it or less to keep ashfaultine at bay. ISX is notorious for making ashfaultine in fuel system as a normal process. Some mechanics use it as an excuse to blame it as being soot or algea in the fuel by mistake, and places like speedco will put in a 50-mocron filter in them like a bunch of idiots. Since You cannot get a primary fuel filter that is only 10 micron from what I have seen, having the davco and using finer filter keeps it at bay long term. - Keeping water out of the fuel system is important too, so this definitely warrants having it repaired or replaced.
