I have a 1996 Tacoma. Just replaced the box, but while doing so I must've gave the fuel filling neck quite a bump.. Now I cannot even put a little bit of gas in because she leaks like a sieve between the flange on the neck and the tank.. It being a 96, any suggestions on how to get these rusted bolts off w/o snapping them ? - I have a new filler neck, gasket and bolts
