Diesel Bug?

Coval Aquasolve - from the website the stuff is a surfactant. Surfactants are soaps by any other name, dosed in fuel and water they would allow more water to dissolve into the fuel than straight fuel will allow.

The water does not disappear its just dissolved hence as it passes through to the engine and gets combusted........ the water will in the long run probably damage engine components. I doubt that aquasolve would have much effect on gross water contamination since there is a limit to how much water you can dissolve in fuel before it becomes maxed out.

there is no magic ingredient ,its a matter of housekeeping, water must be kept out of fuel to keep the bugs at bay. fuel temperature also has a part to play, most diesel engines have a return to tank that gets quite hot, if you have small tanks over time the return flow can heat the whole mass of fuel in the tank, with aviation fuel at 30 deg C I used to grow fuel bugs in 3 hours -something to think about!!

The website also makes claims for its use in aviation fuel I doubt this would ever be allowed.

Treat with a Biocide.

Remove the water before you do anything else.

I would not look to dissolve more water into the fuel.

If you get water through to injection pump and injectors on a non common rail engine budget £4 to 5K per engine if common rail the £7 to 8K per engine so don't mess around remove the water.
