1998 Honda Civic EX standard is leaking fuel from under the left side of the engine just under the spark wires. Why would it leak from there?

It leaks a large amount of fuel right
when the key is turned to the last
position just before turning it over.
It's a rather large leak and I don't
understand how it's leaking from the
left side under the spark plugs as I
thought the fuel compartments for
the engine were in the back of the
engine. What could be the problem?
