My previous boat was an Ericson 2-30, which came with an Atomic 4 engine. If your neighbor's boat originally had a gas engine, the tank has a filter at the end of the pickup tube. Try removing the pickup tube and see whether the filter is clogged. You can clean it with a solvent, or remove it completely. Your primary and secondary filters are enough.
