When looking for fuel filters for 6.7 Cummins, you need to appreciate that they do not provide the same performance. This is why you should target picking only the model designed to work with your car.
Here are some useful tips to help you pick the best:
What Happens If You Do Not Change the Fuel Filter on Time?
Once installed, your car’s fuel filter’s pores are progressively blocked by debris and small particles which tend to make it less permeable. You can notice this from declining engine efficiency. So, if you fail to change the filter on time, here is what you are likely to experience:
- Lack of engine power: Because dirt filters are unable to block dirt, your car’s ECU will signal automated action, resulting in low engine power. On the dashboard, you are likely to get a light indicator for “Limp” mode.
- Vehicle Stalling Under Strain: A blocked filter is likely to become an obstruction for fuel movement, creating a major deficiency for the engine. This is likely to result in loss of engine power, especially when trying to accelerate.
- Random engine misfire: If you notice your car misfiring regularly, especially under heavy loads, the problem is likely to be caused by a used-up fuel filter. It could even result in further damage to the engine.
- Engine component corrosion: If the fuel filter does not separate water effectively, there is a risk of the engine’s internal parts getting corroded.
Factors to Consider When Selecting Fuel Filters for 6.7 Cummins
This is the single most important factor when picking a fuel filter for your car. Well, each car model comes with its own limitations, such as size and design, and it is prudent to check the model that will fit and work with your vehicle.
To be sure of this, consider checking the filter model on your car and order a similar one. Most car filter manufacturers can also tell you the right filter model based on the type of car.
When designing the fuel filters, manufacturers are very specific about the type of fuel they deal with. The filters for gasoline cars are different from filters for diesel cars. Although you might find some models that can work for a wide range of fuel categories, the model designed to work with your specific model guarantees better performance.
The Filter Type
Fuel filters can be classified into in-tank, in-line, primary & secondary, and cartridge & spin models? Your focus should be to identify the model that works best for your vehicle. For example, the cartridge & spin fuel filter design is the most preferred model because of its high-efficiency filtration capacity. However, most of the filters in this category are never cheap.
Once you have purchased a replacement fuel filter, it needs to be installed correctly in your car. If you need a mechanic, that means additional costs for you. Therefore, it will be a good idea to look for a model that is easy to install. Remember that to install any fuel filter correctly, you will require the right tools, including:
- Drain pan
- Wheel chock
- Work light
- Oil filter wrench
- A set of screwdrivers
- The right socket and ratchet
