For a gas boat used in the developed world, I'd probably throw away one,
maybe two of the filters and use a piece of hose. A car uses only one gas
filter, after all...

Good point, perhaps the other gloom and doom posters should pay attention to
that.
The filter in question is mostly for water separation, I also have a glass
inline, mostly to be able to monitor fuel flow and the final filter in
integrated in the engine.
