I had to track down a fuel problem that was driving me nuts. I had random 
shutdowns that would randomly fix themselves. I ended up with a fuel pressure 
gauge and 2 vacuum gauges, one on each side of the filter. I noticed the vacuum 
would increase on BOTH gauges when there was a shutdown, indicating that the 
restriction was prior to the filter.
What it turned out to be was the fuel fill line was coming apart internally and 
dropping a lot of rubber bits into the tank. They would get sucked onto the 
fuel pickup tube and then fall off later.
Ever since I have had a fuel pressure gauge visible from the helm. I got one 
off FleaBay that has a red warning light in it that comes on below 1 PSI. Note 
that a vacuum gauge only tells you if there is a clog, low fuel pressure for 
other reasons lie air in the system or a failed pump leave it sit on 0.
If memory serves I sent one of my extra vacuum gauges to a member on the list. 
I still have one permanently installed.

A crew member advised he had an intermitent mystery fuel problem that turned 
out to be a blockage in the fuel supply line at the tank.
