Manufactured in China, it's an affordable fix that gets your pressure washer, generator, go-kart, or other equipment back in service fast. No UPC or MPN, but it does the job perfectly. Just make sure your engine model matches before ordering. Don't let a missing $5 part keep your $500 equipment idle – keep a spare on hand or fix that leaky tank today!
