you guys are all on crack.
drive your car till its bout empty. drop the tank, should be a few freakin bolts. get some rough sandpaper and grind around the hole a bit. get the JB weld, and a small piece of aluminum [sand the aluminum up too] and put a healthy amount of JB weld around the hole, and put the aluminum on it. then sand the top down, and put more jbweld on it and your done.
you all are making it seem like its a 5 inch ****ing tear in the take. its a ****ing PINHOLE. prolly as bit as the letter "o" on your screen.
so stop being a bunch of *****es. gas is not a magical substance that will permiate thru that tiny PATCHED hole. just stop drilling into your tank for chris'sake.
