What is the maximum fuel pressure for fueling a jet?

The maximum fuel pressure for fueling a jet, specified at 55 psi, is set to ensure that fuel is delivered effectively and safely to the aircraft's fueling system. This pressure aligns with operational standards for jet fuel delivery, allowing for proper flow rates while preventing the risk of fueling system damage or leaks.

Maintaining this pressure is critical for a number of reasons. Higher pressures can lead to issues such as over-pressurization, which may damage fuel lines and connections. On the other hand, lower pressures could result in inadequate fuel flow, potentially causing delays in the fueling process and affecting operational readiness. Therefore, the specification of 55 psi represents an optimal balance to achieve efficiency and reliability during fueling operations.
