well amoffitt , you have to first disconnect your fuel lines running to the gas tank be very careful cause even though you have the car off battery dis connected there is still fuel sitting in those lines ones you have those off and out of the way then take off the gas tank there is usually two hold down straps underneath im not exatcly sure but i think usually 4 bolts take those out gas tank will drop after that u will see the top of the tank undo the screws off of that but make sure u have the tank stable on something like ground something that wont like the tank is on an angle or something like that for the fuel to tip out then once u do that take off that top i talked bout previously and u will see the part try replacing that.
