Thunderbird V8-302 5.0L HO (1992)
Fuel: Testing and Inspection
WARNING: Put any drained fuel in an explosive-proof container.
A fuel sample should be drawn from the bottom of the fuel tank so that any water present in the tank will be detected. The sample should be bright and
clear.
If the sample appears cloudy, or contaminated with water (as indicated by a layer at the bottom of the sample), this procedure should not be used, and the
fuel system should be cleaned.
1.
Using a 100 ml cylinder with 1 ml graduation marks, fill to the 90 ml mark.
2.
Add 10 ml of water to bring the total fluid volume to 100 ml and install a stopper.
3.
Shake vigorously for 10 to 15 seconds.
4.
Carefully loosen the stopper to release pressure.
5.
Close the stopper and shake vigorously again for 10 to 15 seconds.
6.
Put the graduated cylinder on a level surface for approximately 5 minutes to allow adequate liquid separation.
If alcohol is present in the fuel, the volume of the lower layer (which would now contain both alcohol and water) will be greater than 10 ml. For example,
if the volume of the lower layer is increased to 15 ml, it will indicate at least 5 percent alcohol in the fuel. The actual amount of alcohol may be
somewhat greater because this procedure does not extract all of the alcohol from the fuel.
