I think I have a fuel week

[fordF250]

Well I think I have a fuel leak, every time its wet and I pull in somewhere and get out I have a rainbow color puddle under my truck. Its usually about center of the oil pan, but I dont think oil would be rainbow colored. Also what is the pump inside the frame like right under the cab, it has a line coming out it that spirals up. Not exactly sure it is but im guessing its your lift/feed pump. Where does that line go? Just wondering if there are any thoughts of where to look, but if i am leaking its not much.

OBS fuel pump is up in the valley.trace the fuel leak upword. usualy fuel is found in the valley ( if it is the pump, filter ot fuel lines to the filter) and runs down the back of the block.
