## Other bulletins for the same vehicles and component

- [03\-087 \(E295\)](/bulletins/10232496.md), 2023-03-06, Service bulletin: FUEL SYSTEM, OTHER:FUEL FILTER; ENGINE AND ENGINE COOLING. Certain Model Year 2021\-2024 chassis with PACCAR MX engines and optional fuel filter restriction virtual gauge may display incorrect restriction levels. The virtual gauge will be temporarily disabled until a revised sensor strategy is developed.
- [43\-071](/bulletins/10201965.md), 2021-10-05, Service bulletin: FUEL SYSTEM, DIESEL. Fix\-As\-Fail – Due to undersupply issues, only a limited supply of Diesel Exhaust Fluid \(DEF\) sensors are available. As a temporary solution, after PACCAR confirms a DEF sensor is not available, a temporary software update will allow a vehicle to continue operation with a failed DEF sensor by disabling the DEF sensor diagnostics.
- [21KWC](/bulletins/10198759.md), 2021-07-06, Service bulletin: FUEL SYSTEM, GASOLINE. Safety Recall – Cummins Fuel Rail Leak – NHTSA ID: 21V391 / TC: 2021\-323, Cummins Recall: C2423. Cummins PX9 and ISX12 fuel rails may leak around a sealing washer, potentially resulting in fuel leaks. Undetected prolonged diesel fuel spray in the presence of an ignition source may increase the risk of fire.
- [44\-030](/bulletins/10164402.md), 2019-09-05, Service bulletin: FUEL SYSTEM, DIESEL. Fix\-As\-Fail \- Nylon fuel lines may be too short, potentially resulting in a cracked or loose, low pressure fuel fitting at the engine or fuel tank, which may introduce air into the fuel system resulting in a hard\-to\-start or no\-start condition.
- [44\-029](/bulletins/10136234.md), 2018-05-07, Service bulletin: FUEL SYSTEM, OTHER:FUEL FILTER; ENGINE AND ENGINE COOLING; SERVICE BRAKES, AIR:DISC:CHAMBER. Non\-Safety Campaign \- The coolant lines connected to the fuel filter may interfere with the brake chamber on certain T680/T880 vehicles. Repeated interference may cause the fittings to break and leak coolant.
