Fuel pressure takeoff/max

Fuel pressure takeoff/max

• A. 7-25 psi
• B. 0-7 psi
• C. 25 psi max
• D. 5-15 psi

Answer: (C)

Fuel pressure is kept within a safe window by a regulator, and during takeoff the key limit is the highest pressure the system can safely reach. That upper limit is 25 psi. Keeping pressure at or below 25 psi ensures proper fuel atomization and metering without overloading the fuel system components, such as injectors, lines, and seals. Exceeding this limit can lead to flooding, leaks, or excessive wear, especially when the engine demands the most fuel during takeoff. The other options describe ranges or much lower values, but the question focuses on the maximum allowable pressure, which is 25 psi.
