Question

Quizplus · Accepted Answer

The difference between any two fuel injectors should not exceed 1.5 PSI during a fuel injector pressure drop test. This is because fuel injectors working at different pressure levels can affect the engine's performance and cause uneven fuel distribution. A difference of 0.4 or 15 PSI would be too low or high, respectively. A difference of 14.7 PSI is equivalent to atmospheric pressure and not relevant to the pressure drop test.
