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.
