What's wrong?
The 2008 Workhorse R20 chassis uses a Caterpillar C7 engine with metal fuel lines that carry fuel to the common fuel rail. The common fuel rail is a pressurized tube that feeds fuel to the engine's injectors, which spray fuel into the cylinders. Those lines have to stay sealed while the engine vibrates and heats up.
On affected R20 chassis, the number 5 and number 6 fuel lines can crack where they fasten to the common fuel rail. That fastening point is a stress area: the line is held in place while engine vibration and pressure continue around it. Once a crack opens, fuel can leak at the rail instead of staying inside the fuel system.
There is no warning sign before failure. After a leak starts, an owner or technician can notice fuel odor, wet fuel around the engine, or visible fuel dripping near the rail.
