Over time, wear, mineral buildup, or seal degradation can reduce fuel pump efficiency, leading to stalling, misfires, or poor acceleration. Signs include sputtering at high speeds or failure to start. Routine inspection, cleaning the pump filter, and replacing seals every 60,000 miles help preserve performance.
