Hey there, if you're tired of losing the gas cap to your Briggs & Stratton lawn mower or small engine, this 2-pack is exactly what you need. These are direct replacement fuel tank caps (part #594061) specifically designed for the 675Exi and 725Exi series engines. The best part? They come with a little tether (a short cord) that attaches the cap to the engine itself, so it dangles right there when you're refueling – no more dropping it in the grass or losing it forever. Each pack gives you TWO caps, which is perfect because let's be honest, having a spare around for your other equipment or just in case is never a bad idea. It's a simple, affordable fix that saves you a trip to the small engine shop. Just unscrew the old one and screw this new one on. Keep your fuel clean and your engine running smooth.
