I imagine it would take day's to pour a couple of thousand litres through a hand held funnel.

Dave asks a good question.

The Racor Fuel Filter Funnel #RFF15C or Shurhold Industries "Mr. Funnel" #F15
(both @ 10" H x 8.5" diameter) filtres/pass* about 15gpm.

The much more expensive Baja Filter (@ 18"H x 6.5" dia.) only has a maximum flow rate of about 4gpm.

* These filters are capable of removing free water and solids down to .005 inch but will not remove emulsified water; which requires a turbine type water separator (Racor "Spin-On", et al).

In "thirstier" applications (larger fuel capacities), it may not be practical to pre-filtre [u]all[/u\ your fuel yourself; but you can pre-test the supplyer's fuel. Run the first few gallons of fuel through a filtre-funnel, then inspect the funnel for contamiation. Only then (if relatively clean*) pump directly into your tank. I'd recommend supplementary test samples ever 50 gallons or so.

* If, however, you find any contamination, I'd recommend slowing down and using the funnel for the whole refueling process, or seek another source.

Boats with larger tankage are likely capable of installing more sophisticated on-board filtering schemes, hence somewhat less liable to fuel problems.
