How much JP5 is used for DFWD testing?

• A. 800 mL
• B. 600 mL
• C. 400 mL
• D. 1000 mL

Answer: (A)

For DFWD testing, a precise volume of JP-5 is specified to properly prime the test circuit and allow reliable observation of the system during the test. Using 800 mL provides enough fuel to fill the required portions of the test loop so you can verify flow paths, valve operation, and any potential leaks, without overfilling or wasting fuel. Too little fuel could leave air pockets that mask leaks or misread indicators; too much fuel risks overflow or exceeding the test setup’s capacity. Therefore, 800 mL is the appropriate amount for this procedure.
