Diesel engines are known for their durability and ability to perform in extreme conditions. However, one thing they don’t tolerate well is air in their fuel systems. Air in the fuel system can disrupt the flow of diesel fuel to the injectors, leading to hard starts, reduced engine power, or, in severe cases, a complete failure to start.

Signs of Air in Your Diesel Fuel and Airlock Symptoms
