Question

Quizplus · Accepted Answer

Technician A is correct because the specified pressure range (75-90 PSI) is commonly recommended for cleaning injectors to ensure effective cleaning without damaging the fuel system components. Technician B's advice to use a 2:1 mixture of solvent to gasoline for pressure cleaning the fuel system is not a standard practice and could potentially damage the fuel system or engine.
