How to Remove the Gas Tank From a BMW 325
1. Disconnect the negative battery terminal first using a wrench. Engage the parking brake. Slide a drain pan underneath the gas tanks drain plug, before removing the plug and allowing all of the gas to drain out.
2. Remove the bottom seat cushion, then remove the covers on either side of the seat. Raise the rear of your car with a jack, placing a the car onto a pair of support stands. Detach the rear muffler section and driveshaft before attempting to remove the gas tank. To do this you will have to loosen the bolts holding the various components (ie. driveshaft and rear muffler section) into place. Spraying some penetrating oil onto the bolts may make it easier to remove them.
3. Detach all fuel lines connected to the tank using a specialized BMW fuel line removal tool you can find at most auto parts stores. Place another jack beneath the tank as you remove the straps holding the tank in place. The straps are secured with bolts on each end, which you will have to loosen with a socket wrench. Once youve removed all the straps and bolts, the tank will drop onto the jack.
4. Detach all fuel lines, filler hose and fuel pump from the tank while it sits on the jack. Perform any necessary repairs or replace the tank by reversing the previous steps. Finally, lower the car from the support stands and refill the gas tank.
