    Serviceable & Wear Items: Please note that fuel filters, strainers, and rubber components (seals/grommets) are considered maintenance items. While these are protected against manufacturing defects, the lifetime warranty does not cover replacement for items that have reached the end of their functional service life due to normal debris accumulation or natural material aging (such as cracking or swelling from long-term fuel exposure).

    This warranty applies only to the original purchaser and is non-transferable. Improper use or installation voids the warranty. Quantum is not responsible for incidental costs resulting from product failure. Contact customer service to troubleshoot, diagnose issues, and file a warranty claim.
