The Consumer Protection Safety Commission has issued a recall on Briggs & Stratton Portable Generator Fuel Caps, due to fire hazard.

Consumer Product Safety Commission

According to the recall, the caps lack a vent hole, which can allow pressure to build up inside the tank, posing a fire hazard. The CPSC urges you to stop using your generator immediately and check to see if you have one of the recalled caps:

This recall involves model B4363GS fuel tank replacement caps made by Kelch/Bemis for Briggs & Stratton portable generators that use a plastic non-vented fuel tank. The fuel tank replacement caps are black and are missing the vent within the clear lens covering the fuel gauge. The fuel caps can be identified by visually inspecting the clear lens for a vent hole towards the bottom of the gauge. The caps are about 2.5 inches in diameter and 1.25 inches in width. Two 5.5 inch metal rods extend from the bottom of the caps to support a float that moves the needle in the fuel gauge. The fuel tank replacement caps have KELCH stamped into the bottom of the cap. - CPSC
