← TechnologyWhich outcome occurs when regenerative pump clearance increases due to wear in aircraft fuel system?
A)Reduced discharge pressure at high altitude✓
B)Increased fuel temperature from viscous losses
C)Elevated engine vibrations due to fuel pulsation
D)Fuel starvation from vapor lock formation
💡 Explanation
When regenerative pump clearance increases, fluid recirculates internally due to reduced flow resistance, diminishing its ability to maintain design pressure, especially in low-density atmospheric conditions (high altitude). Therefore, reduced discharge pressure results, not increased fuel temperature, engine vibrations or starvation, which have different root causes.
