Water in the fuel is the most common cause
of stalling. Remember that the factory fuel filter will allow
water to pass once it fills to a certain level with water. If
the water in fuel light malfunctions the water can pass into the
system unknowingly to the operator. The water will also carry
bacteria which feed on the diesel fuel. Not only will the fuel
system need removed and cleaned the tank, inlet line and hoses,
as well as the filter will need to be cleaned out. A Biocide can
be used to kill the bacteria and filter it out but alot of people
choose to physically clean the tank and fuel lines.
