Cummins 6B 5.9L Fuel Pump, Remanufactured (3935787)

Has a failing fuel pump brought your diesel engine to its knees?

We know the problem…and we have the solution!
Considering the tight tolerances, and the many moving parts involved, diesel fuel pumps have multiple opportunities for failure. The main cause of failure is due to poor quality or contaminated diesel fuel. Proper fuel hygiene and fuel system maintenance is critical to keeping your diesel engine running at peak performance. Lack of proper fuel system maintenance and the use of poor grade or contaminated diesel fuel can wreak havoc on all the sensitive fuel system components and lead to expensive repair costs.

Diesel fuel pump failure symptoms usually include:

• Rough Running Engine
• Hard Starting
• Engine Misfires
• Engine Stalls
• Engine Stoppage
• Overall Loss of Engine Power
• Excessive Exhaust Smoke
• Unusual Engine Noises
