Exclamation Major Fuel Leak on my 02 7.3 Excursion.

I was driving yesterday and stared smeeling fuel really strin in the cab, I pulled over and fuel was pouring out of the passenger front wheel well. When I returned home the fuel was still pouring out and I was unable to visualize where the leak was coming from. I removed the battery holder on the passenger side along with the washer bottle, and AC control air tank, and all that I have been able to see is fuel soaked insulation over the wheel well. On idle the leak seems to stop and is only pouring out during heavy driving. I replaced all of the seals on the fuel bowl a few months ago and put in a new fuel drain valve and seals and no fuel seem to be coming from any of those areas.
Any suggestions?

strange because fuel lines come up behind the alternator & power steering pump on the driver's side. Do you have an aftermarket fuel system?

There is a fuel line from the bowl to the rear of pass fuel rail in head. Has a bracket that likes to rub a hole in the line.

Could be the fuel bowl drain valve. It The only place I know of fuel will drain out the front passenger side.

So it turned out to be a bad fuel injector cup. Apparently the fuel was leaking around the injector and mixing into the cooling system. The fuel I was smelling was actually leaking out of my overflow bottle in my radiator whenever my engine was under load or hot. It ended up being a very costly repair. Now that the injector cups have been replaced on the engine the issue has been resolved.

Oh that woulda been easy if you could tell it was coming from the coolant bottle.
Expensive? Shouldn't have been that much.

wait,... what?! you smelled fuel, and pulled over to investigate. then you continued to drive not knowing where the fuel was coming from? i would've been calling a tow truck. just sayin'

glad to hear you got it figured out and fixed. and thanks for telling us about it, so the rest of us might know where to look if we experience a similar situation.
