Default Gas Leak-Not due to cold weather.

This just happened last night, I was at a stop light and I stalled out (I just recently started driving a stick shift) and on my way home, everything was fine (approx. 15 minute drive, on the highway ranging from 70-80mph) but when I got home and was in the driveway, I noticed a raw fuel smell in the cabin. I didn't think much of it, went inside and thought it would be gone in the morning.

This morning, I go in the car and still smell the raw gas in the cabin, I tried to start the car and it took longer than usual. As I'm driving to school, the smell still persisted, I had to crack the windows to breathe.

I get to school, pop the hood, and look around the engine bay and I look at the passenger side of the engine bay and I see a stream of gasoline protruding. I'm not really experienced with working on cars so I don't know exactly what I'm looking at. Here's a picture of the stream, it's camera-phone quality, but you can definitely tell what's going on.




In the middle of the picture, there is that black metal piece with little white bubbles on it. From what I can tell, there is a steady spray of sprinkling gasoline. I can't tell what's exactly going on. I'll try to get better pictures of it.

Can anybody here tell me what they think? Any advice would be very helpful.

Edit: I found out that the fuel injector is leaking. I drove it around, revved it up to 6K and then parked it to look under the hood again. The stream of fuel is less, so I'm guessing it's just loose? How do I tighten it to secure the fuel flow?

most likely the o-ring shrank or cracked, search around the injector installation threads for the "how to". You can find a replacement o-ring cheap at your local ace hardware but be sure it is viton.

The car was stage 4 with a vf39 and STi Pinks, but it has since then been downgraded to a TD-04 and the stock injectors put back in.

Also, will it be safe to drive it, it is my daily driver.

For future reference to anyone reading this...if you smell raw fuel...DO NO DRIVE AROUND AND HOPE IT WILL FIX ITSELF.

A good plan would be to grab a fire extinguisher and see if you can find and fix the leak.

Well, It's my daily driver, and tomorrow's going to be the last day it's going to be driven until I get it fixed. Also, it's only dripping now. Nothing's spraying anymore.

Jwhitey: Yes, please tell me. My fuel injector is the one at the top left that's leaking if you're facing the engine bay from the front of the vehicle.

Cool I am going to check mine out tomorrow after I get off work. My car is mostly a garage queen during the work week, and then driven on the weekends. It was my daily driver at one time but I thought I would save some miles on her. I am going to see if mine is leaking/ spraying for sure and I will let you know what is going on with mine and maybe you are having the same issue.

Does anybody know if I have to worry about fuel pressure when I disconnect the injector? What are some things I need to know before I start pulling things out so I don't hurt myself?

Okay. I'm finally getting around to working on my car (and no I havne't been driving it lol) but I do need to ask a couple of questions..

1.) Do I need to replace the seals as well as the O Rings?
2.) What is the size for the O Ring that I need?
