Dirty Hands Working on a diesel truck engine

Keeping your fuel system maintained will prevent premature parts failure and poor running conditions. Here are some important aspects of diesel fuel system maintenance, to keep your fleet running smoothly. While your system and components should typically be serviced by a professional technician, there are some things you can be conscious of that will go a long way toward keeping your engine in good shape.

Air - Air in the system causes all kinds of issues, from hard starting, poor running conditions, or an engine that won’t run at all. If too much air gets in the system, the fuel pump won’t be able to deliver fuel, and the engine will stall, die, or fail to start. Air enters the system via a leak or a bad seal - a deteriorated o-ring, worn components, faulty hose, or otherwise. Keep lines and connections in good shape, and have the leak tracked down if you notice air in the system. A leak will need to be diagnosed, repaired, and all air bled from the system to keep you running smooth.

Dirt - Dirt in the system is a pretty obvious issue - it’ll clog the filters, and if for some reason it makes it further down the line, it’ll block injectors or cause them to stick as well. It doesn’t take much dirt in the wrong place to cause a lot of trouble; make sure your filtration system is in good shape, and only use quality filters and components. Our technicians have the equipment and knowledge necessary to thoroughly clean all diesel components.

Water - Water is damaging, and it only takes a little of it to tear something up or make your engine run poorly. Water traps must be emptied, and filters cleared if any water enters the system at all. Essentially, the goal is for fuel to flow with no interruptions from the tank to the cylinder. Anything that disrupts that process will cause a problem. Fuel system flushing is a good way to ensure everything stays clean and in good shape - when performed by a professional technician, it’ll save you a great deal of trouble in the long run. There are contamination kits and processes that will clear water and other contaminants from the system.
