Is water in fuel a common problem ?

Wow, why not FILL the tank with water and toss in a BIIIg dose of that stuff. Cheap motoring...lol

"It converts the water into the fuel "
Perhaps you would care to re-word. As stated it is obviously rubbish because you cannot convert water into petrol or diesel!

Lighten up.

What he means is that it absorbs the water and allows it to pass through with the fuel.

I used to run a jetboat in Fiordland in NZ and its the one of the wettest areas in the world and all our fuel was carted in Jerry cans.

We used to dump about a hallf gallon of Meths into each 24 gallon petrol tank to absorb any water that got in when filling.

worked a treat.

If the fuel concerned was an Ethanol mix (E10), it absorbs water from the humidity in the air. The longer the time the more water. The water then goes to the bottom of the tank, taking some of the Ethanol with it.
Ethanol is also a great solvent and will clean all the gunk out of the fuel system and take to they filter and sometimes beyond, causing all sorts of engine problems.
Ethanol also gives less power per litre than standard fuel, so uses more to go same distance (3% to 7%).
As for the fuel treatment, there are such items and they do work within reason. What happens is the dry fuel treatment forms a coating around the water molecule's, allows to travel through the system and get inducted in the normal cycle with clean fuel vapour. There is of course a limit to the amount of water it will treat and allow to be effective in the induction cycle. These products "Dry Fuel" by Quicksilver is one, have been available for many years for Marine use and do work well.

Come across a disco diesel at the pumps one day and the bloke put some brake fluid in, says he has been doing it for years to disperse any water in the system.
I had never heard of it before, i use regular doses of the chemtec diesel additive, seems to work ok.

"Never run your tank out of fuel as it will draw the heavier crud at the bottom of the tank through the fuel system."

The fuel pickup is in the bottom of the tank. The heavier crud is in the bottom of the tank. Why would running out of fuel make any difference?

Lex M, Because thats all thats left !!!. CRAP! There is a gap between the sediment and fuel pick up point, No fuel then under suction the crap can be drawn up the line till the thing stops.


Cheers Axle.

pickup isnt in the bottom, its just above to allow the bleep and water to settle
