Whether you decide to to any testing or not, keep a good anchor ready going through that long and tortured channel you mentioned. If you decide to do some testing, buy a vacuum and fuel pressure tester that measures to about 10 PSI and vacuum to 30 inches mercury. This is not for fuel injection pressure measurements, which are ten times what this gauge measures. This tester is for engines with carburetors. The vacuum tester can be used for setting up low idle jet, just adjust jet for maximum RPM while adling. Be sure to clamp all fittings as you do not want gasoline in the bilge. The pressure gauge should read about 3.5 PSI for a good fuel pump. I prefer engine driven mechanical pumps as I think they are more reliable than electric.
Ignition spark tester goes inline between spark coil and distributor. It flashes when there is a spark. If no spark that really narrows the problem down to the electronic ignition system.
You can search online for these items.

Reason: Anchor and 3.5 PSI
