“Briggs & Stratton Fuel Cap Recall: Fire Hazard Due to Missing Vents.” GovInfoNow, updated October 11, 2026. https://govinfonow.com/recall/3486-briggs-stratton-fuel-cap-recall-fire-hazard-due-to-missing. Based on CPSC recall #8421 (https://www.cpsc.gov/Recalls/2019/Briggs--Stratton-Recalls-Portable-Generator-Fuel-Tank-Replacement-Caps-Due-to-Fire-Hazard).
Why it’s dangerous
The recalled caps are missing a vent hole within the clear lens covering the fuel gauge. This absence prevents pressure from escaping the fuel tank, allowing it to build up and potentially leading to a fire hazard during normal operation.
Who’s affected
Owners of Briggs & Stratton portable generators equipped with plastic non-vented fuel tanks who purchased the specific replacement caps from February 2017 through February 2018. These individuals are at risk of fire if they continue to use the unvented caps.
How to tell if you have this one
Check if your cap is model B4363GS, made by Kelch/Bemis for Briggs & Stratton. It will be black with KELCH stamped on the bottom, about 2.5 inches in diameter, and feature two 5.5-inch metal rods extending from the bottom. Visually inspect the clear lens of the fuel gauge; if there is no vent hole towards the bottom of the gauge, it is the recalled item.
