Main Causes Of Cummins Injection Pump Failure And How To Avoid Them

If you have just invested in your first Cummins injection pump, you would want to see that it lasts for as long as possible.  You need to know the main causes of pump failure as well as how to avoid them. 

One of the things that could cause your injection pump to fail is running out of fuel. The pump can be damaged by incorrect bleeding, which is required after the fuel tank runs dry and is refilled.  There are some types of vehicles which require the diagnostic equipment to be bled correctly. To stay on the safe side, make sure that your vehicle never runs out of diesel.

Another thing that could cause a Cummins injection pump to fail is the modifications that are done to it. Certain engine tuning can raise the pressures of the pump and cause thermal overheating, something that can shorten the life of the engine. Also, some cetane-boosting diesel fuel additives, if incorrectly dosed, can affect the lubricating quality of diesel fuel and increase internal pump wear.

Misfueling is another issue that could cause failure of your injection pump. If you accidentally fill up your diesel engine with petrol, the pump can get damaged before the engine even starts. This is because petrol has zero lubricating qualities for diesel fuel pumps. Should something like this happen, do not even turn on the ignition. Instead, you should seek advice and organize transportation so that the fuel can be drained professionally.

Last but not least, poor maintenance can lead to failure of your Cummins injection pump. Diesel fuel filter housings need be drained annually of corrosion causing water. Even if the manufacturer claims that they can be left for longer, it is a good idea to replace the fuel filter cartridge on an annual basis.
