Cummins is recalling about 2,960 Cummins Onan P5000iDF EFI dual-fuel portable generators because a valve installed the wrong way can let pressure build in the gasoline tank, the Consumer Product Safety Commission announced on November 12, 2026. The CPSC says the pressure can force fuel out or eject the fuel cap, posing a risk of serious injury from fire and burns.

The company has received eleven reports of fuel discharging from a unit or the cap popping off unexpectedly. In one, a consumer was splashed in the face with fuel; no medical attention was needed.

Which generators are covered

The recalled generators are dark gray inverter units that run on gasoline or propane and produce between 4,500 and 5,000 watts, depending on the fuel. Cummins is printed in white on the front and on the handle above the control panel, and the Cummins C logo with Onan P5000iDF EFI is printed on the side. The model and part numbers are on a label on the side of the unit.

They were sold at Camping World, Factory Pure, Northern Tool and AP Electric stores and online at Cummins.com from May 2025 through August 2026, for $1,640 to $1,930. The distributor is Cummins Inc. of Columbus, Indiana, and the generators were made in Vietnam. The recall number is 27-087.

The remedy

The CPSC says owners should stop using the generator immediately and check the model and part number on Cummins' recall campaign page (campaign 7308). If the unit is included, the owner contacts an authorized Cummins service location to arrange a free repair there; Cummins' QuickServe service locator lists them. Cummins takes calls at 800-286-6467 Monday through Friday.

The generator rules that apply to every unit

The recall arrives as households pull portable generators out for winter storms. The CPSC's standing guidance for any portable generator applies here too: run it only outdoors, at least 20 feet from the house, with the exhaust pointed away from windows, doors and vents, never in a garage, basement or crawl space even with the door open, and with working carbon monoxide alarms inside the home. Let a generator cool before refueling, since gasoline spilled on a hot engine can ignite.

A portable generator is connected to house wiring only through a transfer switch installed by a licensed electrician. Plugging one into a wall outlet, known as backfeeding, can send power out onto utility lines and endanger line workers and neighbors.

Electrical, gas, roof and ladder work can cause serious injury. Shut off power or gas first, follow the manufacturer's instructions and local code, and hire a licensed pro for anything beyond your experience.
