Dorman - OE Solutions Fuel Tank Strap P/N:578-449
Dorman 578-574 fuel tank strap for the 2002-2010 Lexus SC430 V8 4.3L and other vehicles holds the fuel tank in place against the vehicle. Replace the strap whenever the tank itself is replaced or serviced.
A rusted, cracked or stretched strap, or a rattle from under the car, can mean the tank is no longer held firmly. Other mounting hardware may be behind a rattle or a loose tank too, so have a shop inspect the tank and its mounting on a lift before deciding the strap is at fault.
This strap fits the 2002-2010 Lexus SC430 V8 4.3L, the 1998-2005 Lexus GS300 6-cylinder 3.0L and the 2001-2005 Lexus GS430 V8 4.3L, and other vehicles as well. It is a direct replacement for the original strap. If your Lexus is not named here, open the "Vehicles it fits" section and check your exact model and engine.
