Smell raw fuel under hood
 
I smell raw fuel from under my hood...what could be some problems other than the fuel damper, fuel injectors, fuel filter, fuel lines, or the evaporation hoses?

You pretty much named it except the fuel filter which is under the car and not in the engine bay. I'd check out the entire fuel system until you find the leak of there is one. Likley the FPD or a rail.

lol. I know. It's in the garage, I just got the intake manifold fully ported/painted/cleaned while i'm waiting for the greddy elbow. Just need to find out whats leaking now.

I had a fuel line snap and spray fuel all over my garage floor. It was a miricle that the whole thing thing didn't go up in flames.

I had a fuel hose come off the metal pipes during an auto-x run!

That could've ended really badly. Fortunately, the car lost power and died as I was passing through the lights.

There is a trick that will run your fuel pump so you can spot the leak while the car is off. I know it's somewhere here on the forum.

Yep, just jumper f/p and ground in the diagnostic box and turn the ignition to 'on'.

it sounds good as i sometimes get a wiff of fuel when i boost so i could check this, but i must be being really thick....if the engines not running and fuel pump and fuel system is on....wont that flood the engine? :uhh:

The injectors aren't being opened by the ecu.

If you lift the fuel rail from the engine block, this is how to check for dripping/leaking injectors.
