Not every automobile diesel fuel system is alike, but all of them need some TLC to stay in top condition. You can handle many of these maintenance tasks yourself, but be sure and refer to your owner’s manual before doing anything. Even if you are familiar with the procedures, diesel engines vary widely and you cannot assume anything. Always check details for your particular model. That said, inspections and repairs of specific areas will help keep your diesel engine purring.

Drain Water Trapped in Fuel System

Sometimes water enters your vehicle’s diesel fuel system with the new fuel you pump into it, but water can also collect due to condensation. Water in a vehicle’s diesel system negatively affects engine performance, and if too much collects, it can cause the engine to stop working. Usually water trapped in a diesel system collects in the system’s lowest area. Drain off this water every day.

Inspect Parts Regularly

Be sure and check all parts on your diesel automobile on a consistent basis. If a line is cracked or even looks worn, replace it with parts made for diesel systems such as an

airdog fuel line. Diesel engines perform in specific ways, and they need specialized components.

Release Air Caught in the System

Air can get caught in your automobile’s diesel system in various ways, including letting your car run out of fuel. Air interferes with the fuel flow from the storage cylinder to the engine. The result is an engine that is difficult to start. If too much air accumulates, fuel pumps will not be able to move the fuel through the lines. Your owner’s manual should give you specific instructions for releasing the trapped air in your individual engine.

You can handle a lot of maintenance on your diesel engine yourself, but make sure you perform procedures correctly for your car, as diesel systems are not created equal. Once you become accustomed to your particular system, taking care of it will become second nature. Your diesel-driven wheels will take you great places.
