If you're working on the fuel system of an older John Deere tractor with pencil injectors, these return grommets are a common replacement part. This pack includes 6 brand new grommets that match OEM numbers R79605, AT27622, and 17721. They're used on a huge list of John Deere tractors, combines, cotton pickers, skidders, and industrial equipment. Popular models include the 1020, 1030, 1520, 1530, 2020, 2030, and many more up into the 9000 series. They seal the fuel return lines on the injectors. Always double-check your specific model and cross-reference the part number with your old grommets before ordering. A small but crucial part for keeping your diesel engine running cleanly and without leaks. Keep a few spares on hand for maintenance.
