Ok first I would sugest that anyone with the problem where the car stalls or stumbles with a low tank to test the fuel pump with a scope and amp probe. This will show you any signs of failure and also show you pump RPM. If you dont have access to this equipment go to a shop that has it and knows how to use it. Here is a link with more info on this. http://www.vetronix.com/pdf/masterte...rtech_tt_4.pdf
Next the trick I learned. First the entire car needs to be lifted. I did this by using ramps on the front and jackstands at the rear. Both rear tires shoud be removed for easier access to the fittings and clamps. Buy a fuel line tool from the parts store, mine costs $3.99 at Auto Zone and was worth every penny. Buy new fuel line clips while at the parts store, again $3.99. Use a floor jack to slowly lower the tank and to put it back in. There is a pesky wire that goes to the ABS sensor on the driver side, undo the connector on the passenger side and remove the clip holding the wire tight, this will give enough slack in the wire so it doesnt snag on the tank when its going back in. And remove the two hangers on the muffler so the exhaust hangs down several inches, just rest the muffler on a bucket. This allows room for the tank to clear the exhaust.
Emptying the tank is the tricky part. I only saw one way to do it and that is to remove the vent pipe on the filler and siphone from there. The total job was about 2.5 hours including smoke breaks (away from the car!!).[/url]
