Nearly 27,000 Kenworth and Peterbilt Trucks Are Recalled Over Fuel Filter Hoses That Could Leak, and Truckers May Smell Diesel

By Big Rig Daily Staff

Paccar is recalling nearly 27,000 Kenworth and Peterbilt trucks because a fuel filter hose on their Cummins L9 engines can separate from its fitting, according to Land Line, which cited National Highway Traffic Safety Administration (NHTSA) documents. A separated hose can cause a fuel leak and an engine stall. Truckers who own these models may smell diesel.

Which trucks are affected

The recall covers these models and model years:

• Kenworth T270 (2022-23)
• Kenworth T280 (2022-27)
• Kenworth T370 (2022-23)
• Kenworth T380 (2023-27)
• Kenworth T480 (2023-27)
• Peterbilt 548 (2022-27)
• Peterbilt 536 (2023-27)
• Peterbilt 537 (2023-27)
• Peterbilt 567 (2025)

What owners may notice

Like the original Cummins recall, Paccar estimates that only 3% of the trucks in the recall population have the defective hose. Owners of affected trucks may smell diesel or notice a leak, and a low fuel pressure warning may come on. As with a similar recall by Daimler Truck, no warranty claims or injuries have been reported, Land Line said.

What the fix is

Paccar will replace the fuel hoses at no cost to the owner. Notification letters are expected to be sent to owners on Dec. 20. Questions can go to Peterbilt customer service at 940-591-4220 or Kenworth at 425-828-5888, using Paccar's recall number 26PACJ. NHTSA's number for this recall is 26V700.

How this fits the larger Cummins recall

Cummins issued an equipment recall in September for its L9 engines. Affected engines have a remote fuel filter hose that can separate from the fitting. More than 39,000 L9 engines are covered, though Cummins estimates only 3% actually have a defective hose. Soon after, Daimler Truck North America recalled a few thousand Freightliner trucks and chassis with the engine. Land Line said more than a dozen manufacturers purchased the L9 engines, and that the Daimler Truck and Paccar recalls account for about three-quarters of all L9 engines being recalled. The rest include buses, cranes, fire trucks, motorhomes and refuse and utility trucks.

Quick facts

• Trucks recalled: nearly 27,000 Kenworth and Peterbilt trucks.
• Problem: remote fuel filter hose can separate from the fitting, risking a leak and stall.
• Share expected to have the defect: about 3%, per Paccar.
• Owner letters expected: Dec. 20. Recall numbers: Paccar 26PACJ, NHTSA 26V700.
