Pumps (Oil & Fuel)

Pumps (Oil & Fuel)

Oil and fuel pumps are essential to maintaining the performance, efficiency, and reliability of diesel engines — whether powering a standby generator, marine engine, or industrial machine. These pumps ensure proper lubrication and fuel delivery across all load conditions, safeguarding the engine against premature wear, overheating, and fuel starvation.

At AMS Parts, we supply genuine and OEM oil and fuel pumps to meet the exact technical requirements of your engine — ensuring reliable performance and long service life.

When Should Pumps Be Replaced?

Pumps are typically replaced during overhauls or when early signs of wear or failure appear:

• Loss of oil pressure or fuel delivery
• Internal noise or excessive wear
• Engine warning indicators for pressure loss
• Oil or fuel leakage from seals
• Routine service interval specified by the OEM
• As part of major rebuild or top-end overhaul
