water sensor has malfunctioned/or fuel has large quantity of water contamination.
Where is the water drain for the Water in Fuel light?
A 1998 Ram with the Cummins diesel has a water in fuel indicator on the dash that will illuminate if there is water in the fuel filter housing.
Water is heavier than diesel fuel
It means that the fuel in gasoline station was mixed with water or water somehow got in gasoline stations or your cars fuel tank. To get it out you can buy some special chemicals which collect water from your diesel in tank, and then burns it with diesel mixed ;) Now if your talking about the idiot light that says water in fuel means need to change fuel filter. sensor on bottom of cap to fuel filter is touching the metal inside filter. all fuel has moister in it. The filter is a fuel separator.
I have got water in the diesel fuel on my bmw 32o d 2004 model how do I drain it off
The fuel water separator is located on the frame rail with the fuel filter, you should drain the water and replace the Filter on the frame rail and the filter on top of the motor if your water in fuel sensor light comes on...
On the fuel filter!
According to my manual, the fuel light goes on when the tank is down to approx 6 litres of diesel.
No diesel is a petroleum byproduct and is not water. If there had been water in the diesel fuel, it may separate after a freeze and thaw.
Diesel fuel is hygroscopic and absorbs water. It's not unusual for diesel vehicles to have water in the fuel. Use a fuel conditioner and water remover, and use the water separator drain if it has one.
The main thing that happens when there is water in diesel fuel is that it will burn poorly or maybe not even at all. It will also sink to the bottom of the fuel tank.
Water is attracted to diesel fuel. Moisture in the air gets in there. That's why you need the special filters for this.
