What's wrong?
The fuel filter assembly on the 2022-2026 Isuzu Ftr, Isuzu Fvr, Chevrolet 6500XD, and Chevrolet 7500XD trucks includes an integrated fuel heater. That heater warms diesel fuel as it passes through the filter area, which helps fuel flow and starting in cold weather. Its housing and electrical connector need to stay cool enough to hold fuel inside the assembly.
On affected trucks, an air pocket sits near the suction port where the heater element operates. Part of the heater is exposed to air instead of being surrounded by fuel, so heat does not move away from the element as designed. Over time, resistance builds at the internal electrical connections. Those hot connections can melt the nylon housing or metal pins, allowing diesel fuel to leak into the electrical connector.
Owners can see fuel around the fuel heater. The truck can also be especially hard to start in cold weather, and a burning smell or smoke near the fuel filter assembly is a warning sign.
