Water in the fuel system

To stop this happening again:
(The shame of it!)

[YOUTUBE]

Does anyone have an idiotproof way of testing the petrol in your fuel tank for excessive water contamination?
This was second time it's happened to me. This is what happened even after filling the 25l tank with petrol, having left about 8 litres before i last used it.
Can you tell just by looking? as i believe water would just absorb, diluting the petrol.

cheers
Martin

Martin, I think you need to do two things, first always keep the fuel tanks full as metal tanks suffer from condensation andsecondly fit a CAV fuel filter. Do a search on ribnet and there is lots of advice.

Definitely a Racor-type water separator, check the gasket on the fill cap, and make sure your vent is not susceptible to runoff from surrounding areas. Of course, you also have to check the bowl on the filter to make sure you're not filling the filter with water (had a near-incident in Hawaii diving off an acquaintances Whaler; the filter canister was several years old, and filled with water, rust, and sludge. Enough to starve the motors of fuel. Removing the bowl and emptying/wiping out the foeign material got it running enough to get back to the harbor.)

Fuel stations use a flourescent dye to stain the water at the bottom of the tank, which then shows up on a dipstick, but that may not be an option depending on your fill tube configuration.

Perhaps regular use of a "Water-Zorb" product?
