In accordance with Coast Guard Regulations (33 CFR), each pressure gage used in fuel transfer operations must be calibrated to indicate pressure within what percent of the actual pressure?

Correct Answer: Option D — 10%

33 CFR 155.785 requires that pressure gauges used in oil transfer operations be calibrated to within 10 percent of the actual pressure. This tolerance ensures that the person-in-charge can accurately monitor system pressures and detect potential over-pressurization or hose failure risks during the critical oil transfer process.
