This may not apply to your sled-but i had a gas leak on my '79 el tigre, and all that it was, was an overflow pipe from the tank. so i plugged it with a wooden dowell, and it doesn't leak anymore. are you sure it is from the belly pan? does it leak 1/4 tank out? i would say check for an overflow pipe or something.

Well i would check the lines running from the tank to the fuel pump and from the fuel pump to the carbs. The reason that i think it has something to do with the fuel pump is cause you said it leaks when you go to start it. I am assuming that you actually mean pulling the cord (or electric starter) when you "go to start it". Pulling the cord will give the vacuum pulse to the fuel pump and thus it pumps fuel. Otherwise i would check to make sure that your floats in the carbs arent stuck dumping immense amounts of fuel into the cylinders and coming out the exaust ports.

I would say do what both of them say. Another thing, if nobody has said, check the plugs on the bottom of the carbs. Make sure that they are not broken or leak. Have a good day!

Dude, don't plug vents from your gas tank! You can implode it then.. Just put the overflow hose up higher than the tank goes, then no more problem.

As for the leak, check for cracked lines, that happens over time.
