Briggs & Stratton Fuel Tank Bushing

Briggs & Stratton Fuel Tank Bushings

A fuel tank bushing is a small part with a big job. It isolates the tank from its mounting hardware, absorbs engine and chassis vibration, and keeps the tank positioned correctly so fuel lines and fittings are not stressed. Over many seasons of heat, fuel exposure and constant vibration, rubber bushings harden, crack or flatten, and a worn bushing can let the tank shift, rub or leak. Briggs & Stratton, the Wisconsin-based small engine manufacturer, supplies genuine OEM bushings made for its own engines and the outdoor power equipment they power.

The 1654930SM Fuel Tank Bushing

The part most associated with this category is the Briggs & Stratton 1654930SM fuel tank bushing. It is a compact rubber bushing, listed at roughly 3/8 x 9/16 x 5/8 inches, designed to support the tank securely and reduce movement and wear. It is documented as fitting a range of riding mower and lawn tractor models, including Craftsman CTX-series tractors with 20 to 30 HP engines and 42- to 54-inch mower decks, as well as Snapper and Simplicity equipment. Always confirm your equipment model number against the fitment information before ordering, since many small bushings look nearly identical.

Why Choose Genuine Briggs & Stratton

Briggs & Stratton has built small engines for over a century. It introduced its Type P portable engine in the early 1920s and developed the lightweight aluminum engine in 1953, and its engines power eight of the ten leading lawn mower brands. That experience informs how OEM parts are specified. A genuine bushing is made to the original dimensions and material, which matters because a mount that is too soft, too thin or the wrong shape can allow tank movement and put strain on the fuel line connections.

• Exact-fit design: OEM sizing means the bushing seats correctly in the tank bracket without shimming or modification.
• Vibration control: The rubber isolates the tank from engine and deck vibration, which helps protect seams and fittings.
• Fuel system integrity: A stable tank keeps lines and connections properly aligned, supporting reliable fuel delivery and reducing leak risk.
• Supersession-ready: The 1654930SM supersedes earlier part number 1726400SM, so older equipment is still covered.

Shopping and Installation Tips

Before replacing a bushing, make sure the tank is empty and disconnected from the engine, then remove the old bushing carefully so you do not damage the surrounding bracket or tank. Inspect the other mounting bushings at the same time, as they have aged under the same conditions. If you maintain several machines or do regular service work, multi-packs of this bushing are also offered by the manufacturer, which is convenient for keeping spares on the shelf.
