(5) If water has accidentally gotten into fuel before addition of the thickener, peptizing action takes place, but the results are unpredictable because the quantity of water added is not controlled.
36. PREPARATION OF LIQUID FUELS.
a. Choice of ingredients. Thin fuels are * * * reaching the target. For this reason, liquid fuels should contain the lowest proportion of gasoline and the highest proportion of heavier fuels that permit easy ignition. In hot climates, * * * of great importance. The gasoline used can be any U. S. grade of motor fuel or aviation gasoline. Suitable blends are as follows:

40.1 USE OF PACKBOARDS (Added).
Detachable pressure tank and valve assemblies ([par. 66.1]) make possible the use of packboards for transporting pressure tanks, 5-gallon cans of fuel, wrenches, and additional ignition cylinders close to the front line of combat to troops using flame throwers. As packboards are not manufactured specifically for servicing flame throwers, standard quartermaster-issue packboards are used. Packboard transportation is practicable only with pourable fuel. (Pourable fuels include some thickened fuels and all liquid fuels.)
a. The following is a suggested procedure for packboard transportation:
