ATV riders - if you're missing a gas cap or yours is cracked and leaking, this universal 70mm fuel cap is exactly what you need. It fits most Chinese-made quads like Coolster, TaoTao, Buyang, and similar 110cc to 250cc models. The 2.76-inch thread diameter is pretty standard for these smaller ATVs, but definitely double-check your existing cap before ordering. What's nice is the built-in vent hole that prevents vacuum lock and the sturdy ABS construction that can handle fuel exposure and the occasional drop on the garage floor. Installation couldn't be simpler - just screw it on and you're done. No tools, no fuss. The black finish looks clean and it seals tight without being impossible to remove when you need to refuel. Beats paying dealership prices for a simple gas cap, that's for sure. Keep your fuel clean and your rides uninterrupted with this basic but essential ATV accessory. Seriously, don't ride around with a messed up gas cap - it's an easy fix that prevents bigger problems down the trail.
