Dorman - OE Solutions Fuel Tank Strap P/N:578-157
Dorman 578-674 fuel tank strap for the 2003-2008 Mazda 6 4-cylinder 2.3L or V6 3.0L holds the fuel tank in place under the car. It is a direct replacement for the original strap and is recommended whenever the fuel tank is replaced or serviced.
A rusted-through, cracked or stretched strap can let the tank sag or shift, which can show up as a rattle from underneath. Before you replace the strap, rule out other sources of that noise, such as a loose heat shield or exhaust hanger. If a worn strap is the cause, this one replaces it.
This strap fits the 2003-2008 Mazda 6 4-cylinder 2.3L or V6 3.0L.
