Cheap Diesel bug killer

I've followed LeighB's advice. As bug lives on the water interface, the simple trick is to keep this below the fuel take-up line, which is about 4" above the bottom of my tank. It is only necessary to drain a gallon or two using the cock right at the bottom of the tank, once a season, to prevent bug jelly getting to the fuel line. I have never had a fuel blockage, or even much sign of bug on the filter at its annual renewal.

Andrew - I would have thought that the motion of the boat in a heavy sea would stir this up. Having had water in my tanks, below the intake level, it certainly got into the filters in a heavy sea. Resulted in having to invoke plan B and sail!

Keep your tank full over the winter period as hot midday temps and overnight falls will induce condensation in tanks. Onec you start boating next summer the goo will get stirred up block filters and then get into the injector pump. How do I know? cos it happened to me.
Drained the tank, fitted new filters two each engine and still had blockages coming back across the English Channel.

Took the extreme measure of fitting replacement engines, fuel tank, pipework and fast change filters. now keeping my fingers crosssed. Did think of fitting a circulating pump and filters to circulate the fuel over the winter, but didn't get round to it, the boat is in a temp controlled shed for the winter so will not suffer from swings of temp.
