When you say you "have a gas leak coming from the front of the motor", where exactly are you seeing the fuel?
Definitely need to find the source for that fuel leak immediately. I would make a thorough inspection before starting the engine again. If that turns up nothing, I would start it momentarily, then look for the source of the leak. As stated above, the fuel line connection is a common source for leaks. Keeping a fire extinguisher handy is always a good plan when dealing with fuel system problems. have a flashlight and a paper towel or two in hand to look for leaks. Sometimes wiping areas with the paper towel will help you track down a leak. There is an overflow line that is supposed to go from the fuel pump to the flame arrestor in case of a ruptured fuel pump diaphragm.
