Technician A connects a fuel pressure gauge to the Schrader valve on the fuel rail. Technician B connects the gauge to the fuel lines by inserting a tee adapter between the fuel filter and the fuel rail. Who is correct?

Question

Quizplus · Accepted Answer

Both Technician A and Technician B are correct because there are multiple valid methods to connect a fuel pressure gauge for diagnostic purposes. Technician A's method of connecting directly to the Schrader valve on the fuel rail is a common and straightforward approach. Technician B's method of using a tee adapter to insert the gauge between the fuel filter and the fuel rail is also a valid technique, especially in systems without a Schrader valve. Both methods allow for accurate measurement of the fuel pressure.
