One owner of a Cummins Onan generator opened the fuel system and took a face full of gasoline. The consumer needed no medical attention, but the report is one of eleven that led Cummins and the Consumer Product Safety Commission to recall about 2,960 dual-fuel portable generators on Nov. 12. The reason is a venting fault that lets pressure build in the gas tank until fuel can spray out or the cap can eject.

The P5000iDF EFI and the sales window
The recall covers the Cummins Onan P5000iDF EFI Dual Fuel Portable Generator in dark gray. It runs on gasoline or propane and produces 4,500 to 5,000 watts, depending on the fuel. The word “Cummins” is printed in white on the front and the handle, the Cummins “C” logo and “Onan P5000iDF EFI” appear on the side, and the model and part number are on a label there too.
Camping World, Factory Pure, Northern Tool and AP Electric stores sold the generators, along with Cummins.com, from May 2025 through August 2026 at prices between $1,640 and $1,930. That is a 16-month window, and the retailer list mixes camping, farm-supply and generator-dealer channels with the manufacturer’s own site.
The recall notice on the CPSC’s Cummins recall page puts the units at about 2,960. As ConsumerAffairs noted in its Nov. 13 recall roundup, Cummins describes the population as nearly 3,000 units. The number is small next to the large fire pit and heater recalls the CPSC posts, but the product is a fuel-burning machine, and the failure involves liquid gasoline leaving the tank.
Incorrectly installed valves and rising tank pressure
Valves were installed incorrectly, so fuel vapors do not vent properly from the gasoline tank. Pressure builds inside, and the result, in the CPSC’s wording, is that pressure “can cause fuel to discharge or the fuel cap to eject.” A generator sits near a hot engine and exhaust, so loose liquid fuel or a cap flying off the tank puts gasoline close to ignition sources, which is why the agency calls the danger a risk of serious injury from fire and burn hazards.
The firm has received eleven reports of fuel discharging and the cap ejecting. In the one that involved a person, a consumer was splashed in the face with fuel. No fires and no burns are mentioned in the notice as summarized by local outlets such as MyParisTexas, which republished the CPSC text.
Because the machine is dual fuel, one question owners will ask is whether running it on propane avoids the problem. The notice as republished addresses the gasoline tank and tells owners to stop using the generator without carving out an exception for the other fuel, so the cautious reading is that the instruction applies to the whole unit until the model and part number are checked. Heat makes the stakes concrete: gasoline vapor expands as a tank warms, which is exactly when a blocked vent builds the most pressure.
Gasoline in the eyes or on the skin is its own hazard, apart from fire. A splash to the face is why the agency’s wording stresses stopping use immediately rather than waiting for a repair appointment. The notice is a hazard warning built on near-misses, which is a sensible time to act, since the eleven incidents show the fault already happens in ordinary use.
Campaign 7308 and the free repair
Owners are told to stop using the generator immediately and check whether the model and part number are included on the Cummins recall page, referred to as campaign 7308. An affected unit gets a free repair at an authorized Cummins service location, found through the Cummins service locator. Questions go to Cummins at 800-286-6467 on weekdays or through the company’s portable generator pages.
The remedy is a repair, not a refund or a replacement, so the generator comes back with its valves corrected. Because the cap ejection and fuel discharge come from the tank venting rather than operator error, there is no handling trick to keep using the unit safely in the meantime. Storm-season owners who rely on the unit for backup power face a gap while a service location schedules the work.
Identification is the first step, and the labels do the work. The model and part number sit on a side label, next to the Cummins “C” logo and the Onan P5000iDF EFI marking, so an owner can read both without opening the machine. Anyone who bought a generator in the window from one of the five sellers and cannot find the label should treat the unit as suspect until the Cummins recall page says otherwise. Refueling is the moment of greatest exposure, since the cap comes off or goes back on when the tank may be warm and pressurized, and the one injury report arose around fuel handling by an owner.
Cummins has built portable generators for years, and a 2010 CPSC recall of a different Cummins Power Generation portable model for a fire hazard is a separate matter, a different product with a different fault. The open question for the current recall is how many of the roughly 2,960 owners will have their units repaired before the next outage season, a figure the agency has not published.
