d) isopropyl
question 13 (5 points)
cloud point is the low - temperature point at which the waxes present in most diesel fuels tend to form crystals that can clog the
a) fuel filter.
b) fuel injector.
c) lift pump
d) injection pump.

Explanation:

Question 12

Methanol is commonly known as wood alcohol. It was historically produced as a by - product of the destructive distillation of wood. Ethanol is grain alcohol, gasohol is a fuel mixture, and isopropyl alcohol has other production methods and uses.

The cloud point is the temperature at which waxes in diesel fuel form crystals that can clog the fuel filter. The fuel filter is the component in the fuel system that is most likely to be clogged by these wax crystals. Fuel injectors, lift pumps, and injection pumps are less likely to be directly clogged by wax crystals formed at the cloud point.

Answer:

C) Methanol
