    Keeping your fuel system maintained will prevent premature parts failure and poor running conditions. Here at R & M Automotive we have tips on the important aspects of diesel fuel system maintenance, to keep your diesel fleet trucks running smoothly - longer.

    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 component, faulty hose, or otherwise. Here we inspect your lines and connections to ensure they are in good shape and track down any leaks we notice air in the system.

    Since the first automobiles, there have been radiators. Every liquid-cooled engine on the road has, and has always needed, a radiator; without it, the engine would overheat in no time, causing catastrophic engine failure. While the efficiency of radiators, the materials they’re made out of, and the shape and size of them have changed over time, radiators haven’t actually changed much over the last century or so. At R & M Automotive we know that even though radiators generally last a long time, they do occasionally fail.
