What's wrong?
The fuel tee fitting on the 2015-2018 Kenworth K370, 567, 579, T680, and T880 trucks is a plastic connector in the fuel return system. It joins fuel lines so unused fuel can move back through the system instead of leaking around the engine. This small fitting has to stay sealed while fuel moves through the hoses, lines, and fittings.
On affected trucks, the fitting was made with the mold temperature too low. As the plastic flowed into the mold, the knit line, where material meets inside the part, became porous. That porous line lets fuel pass through the fitting wall or joint. The result is a fuel tee that does not stay sealed during normal operation.
The warning sign is fuel seen during a visual inspection. Look for drips of fuel around the return fuel tee and the nearby fuel lines. If fuel is visible there, the fitting is already leaking.
