Mazda 6 Fuel Tank

The Mazda 6 Fuel Tank is a closed tank located behind the car that feeds the engine with gasoline and also collects vapours to meet clean emissions requirements. The Fuel Tank is concealed beneath the rear and carries the liquid fuel as well as the electric pump and the level sender that supplies the dashboard gauge. Tall internal baffles ensure that the gasoline does not slosh out of the pickup when the vehicle stops hard or turns quickly, so the pump remains submerged and silent. The Fuel Tank unit is connected to the evaporative emission control system, where the fumes pass through special lines and are not released into the air. Over the generations Mazda provided two construction styles. Stamped and welded steel types provide classic strength but may leak after years of exposure to rain, salt, and road debris, and corrosion may also cause perforation. Subsequent models applied blow-molded shells of high density polyethylene material that is resistant to rust and helps save weight, but the plastic may still be damaged by exposure to extreme heat, vibration, or a sharp impact. No matter the material, all factory Fuel Tanks are leak tested and are provided with a new locking ring and seal to fit at the filler neck. Tank straps are also exposed to the same harsh environment, hence Mazda suggests that they be replaced whenever the tank is changed to ensure the straps are secure. The Mazda 6 Fuel Tank is hidden and out of view thanks to sturdy construction, anti-sloshing baffles, and coupling with the EVAP system, providing the Mazda 6 with uninterrupted fuel flow and cleaner air.
