I want to change my fuel filter,but I need to purge the fuel pressure.Where under the hood is the fuel pump relay?It is a 2002 Mazda Millenia S.
JUST RELEASE THE PRESSURE AT THE FUEL PRESSURE TEST PORT ON THE FUEL SUPPLY RAIL THAT SUPPLIES THE INJECTORS, IT IS A METAL VALVE LIKE A TIRE VALVE, THAT IS THE FACTORY RECOMMENDED METHOD..
If you want to just release the pressure, loosen the gas cap, if you want to purge out the fuel, pull the fuse for the pump,same difference.
