Where is a suction gauge typically located in a fuel oil transfer system?

• A. Before the filter
• B. After the strainer and before the pump
• C. Before the pump and before the strainer
• D. After the pump

Answer: (B)

In a fuel oil transfer system, the suction gauge is typically placed after the strainer and before the pump. This location is crucial for accurately monitoring the pressure within the system to ensure that the pump is receiving the correct amount of fuel oil without air or debris, which could lead to inefficiencies or damage. By placing the gauge here, operators can detect any issues such as increased resistance from a clogged strainer or insufficient suction pressure due to other system faults.

Monitoring the pressure at this point allows for proactive maintenance and operational adjustments, helping to avoid potential failures in the fuel transfer process. Having the suction gauge situated after the strainer is important as it provides a clear indication of the condition of the fuel oil entering the pump, ensuring optimal functionality and performance.
