Anyone know ?

A lit match?

Anything that has a density lower than water and higher than gasoline.

Google a material density chart and see what falls in between the 2.

(Oak wood is one example)

This must be for your water detector.

Specific gravity of gasoline is .760

Specific gravity of water is 1.00

Anything with a specific gravity between 1 and .760 is lighter than water but heavier than gasoline. It will float on water and sink in gasoline.

ty..good info...

Whoever said 'bodies' was on to something - 'Bones, pulverized: 0.88 specific gravity'! Sooooo.... you just need to fill up your tank with bodies & some rocks and wait for them to pulverize the bones

Apparently a couple pounds of butter would also work (sg: 0.87)

Styrofoam, it floats on water and desolves in gasoline.

Stachi - why??

I had an idea pop into my head about a pick up tube that would float on top of any water in a tank so it would only draw fuel....

That won't work. When you're under way that fuel & water are sloshing around and mixing up so there won't be enough water at the bottom to hold up whatever floating material you put on the end of your line. All that water will be suspended in the gas until you stop & it settles again.

Plus... why float your pickup just above the water level? Why not choose a float that floats on top of the fuel and then make a pickup that draws fuel from just below the float, say and inch or two. Of course you'd never want to run the tank all the way down, but if you're worried about water on the bottom of the tank you wouldn't be running it all the way down anyway.

Really small rocks...

Sorry couldn't resist the Monty Python reference...

Eventually, there'd be a lot of water in the tank. Need a way to get rid of it, if said device leaves it all behind.

Probably best to filter the gas going into the tank (when filling) and filter it going out (when running). With this approach, you get it in tiny am'ts and don't leave a bunch of H2O in the tank.

That wouldn't work for the same reason. The water is suspended in the gas when sloshed around. It's suspended in all levels of the gas.

Really if you have enough water in your tank to worry about something like this, you have a bigger problem than just a poorly running engine & you need to get that water out.

I agree. But if he's dead set on trying this, seems pulling the fuel from the top would be a better idea than next to the water line (when sitting still that is).

Either way, ya, not going to work once under way.
