11.02 Why are typical problems for fuel systems?

There are many problems with fuel systems that are based on the initial design of the system. Once a well designed system is commissioned, with any installation errors corrected, they operate as highly reliable systems.

Some of the typical post-commissioning problems for fuel systems are:

• (a) pump or valve activation failure from loose wiring
• (b) loss of prime in suction pump piping system
• (c) leak in piping systems, sometimes due to overstress from thermal expansion
• (d) solenoid valve leakage from seating surface debris or deterioration.
• (e) failure of elements in relays or point sensing elements
• (f) solenoid valve electrical failure
• (g) submersible pump capacitor failure
• (h) failures from line leak detection systems
