Evo 9 leaking gasoline, won't run right
 
Car stalled out yesterday because it quickly ran out of gas. Got it into the air today and saw gas was leaking out somewhere near the exhaust manifold.

Anyone know what this could be?

Thanks

There shouldn't be any gas line near exhaust manifold. Post some pictures.

That's what I thought but its coming from right above the o2 housing in a spot I can't see. Leak is big can't drive the car

It's high time for pictures.

Right at the o2 housing in front and behind it. Ran fine again yesterday then this morning fuel spraying from both sides.

There's no fuel lines anywhere near that area. Are you positive it's fuel? I know it's annoying when people ask over and over but I'm 98% sure there's no fuel lines there.

I know its weird, definitely fuel tho thr car reeks of gas!! Took the downpipe off and could see it dripping out the o2 housing.

In the pic you can see the wet spot on the connection above the housing.

So, trace it back. The closest fuel spot to there is on the other side of the valve cover.

I'm with everyone else, I don't think it's fuel. And if you actually think it's fuel, why are you driving the car still? Gas + Hot = Fire

unless you are dumping so much fuel that it's washing through the engine while you turn it over. it's not running, right?
if it's running and you are seeing fuel (silly question, but it's fuel, no water right?). then definitely not let it run. let the system pressurize and trace the fuel back as recommended above.

Yea the car will run just very poorly while pouring out the exhaust.

Could a stuck open injector flow so much fuel that it could pass through the combustion chamber unburnt and out the exhaust?

theoretically, i suppose. especially if it wasn't closing. that would dump it in and force it out on the non-firing stoke.
