Fuel leak

What is between the head and the up pipe on the drivers side that could be leaking fuel? Both fuel lines from the housing to the heads are dry and nothing in the valley. The leak is small and just started.

There is a 1/8"NPT plug located on the driver's side about the same position as where the fuel line connects to the rear of the passenger's side that could leak but would be rare unless someone pulled it and did not use a pipe dope when reinstalling it.

On the rear of both heads, there is a banjo bolt style of plug that plugs the fuel rail from when the head was manufactured. This bolt (plug) is sealed with an o-ring that can leak but it would run down the rear of the engine.

Thanks for pointing me in the right direction it was the 1/8 plug on the head barely finger tight must have vibrated loose a bit. pulled it out cleaned it and thread taped it and installed. Glad it caught my nose at the gas station and on my day off too.
