How To Choose The Right Cummins Injectors

 

Buying the right Cummins injectors for your vehicle can be a challenging task if you don’t know where to start. The wrong choice of fuel injectors will have your engine running rough faster, and you also risk ruining your engine altogether if you make the wrong decision. So, before you go ahead to buy any fuel injectors, you need to understand the factors to consider.

During your search for the right Cummins injectors, you need to remember that bigger is not always better. You can easily fall into the trap of thinking that bigger fuel injectors equal more power. However, unless you have an engine that is set up to deal with the extra fuel, you will be on a fast track to trouble. The excess fuel will flood the engine making it completely unable to run, or make it run too rich. This can lead to fouled spark plugs and damage to the engine.

The good news is that there are a number of things you can do in order to increase your fuel capacity to accommodate bigger fuel injectors. The main ones include increasing the airflow (which can be done by installing a turbocharger or supercharger, or fitting a bigger throttle body), installing a bigger exhaust, fitting a bigger fuel pump, remapping the computer or adding an adjustable fuel pressure regulator.

But what if you have modified the engine but the Cummins injectors are not delivering enough fuel to keep up? If you have added a turbo, a bigger exhaust, a higher flowing fuel pump, and remapped your computer, you will need bigger fuel injectors. Otherwise your car will run too lean and you will end up with situation where your vehicle is sluggish and lacking in power at best, or at worst, you will burn out the pistons and destroy the motor.
