    Keeping your fuel system maintained will prevent premature parts failure and poor running conditions. Here at Zylstra Automotive & Diesel 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.
