GAS LEAK

2002 Chevrolet Trailblazer • 6 cylinder 4WD Automatic • 130,000 miles

I have a 02 chevy trailblazer and when I fill it up all the way with gas, it starts to spill out from underneath. Any ideas?

It sounds like you have a hole at the top of the tank or a leaking sending unit. You will need to remove the fuel tank to check where the leak is coming from.
