Today I was driving my s4 tII and all of a suden started smelling a strong gasoline smell, first I thougt it was the fumes because I'm runing straight pipe all the way to the mufflers but it was like if you open a gas container, when I got home i open the hood and notice that there was a podle of gas underneath the injectors and it was dripping all the way to the floor, I waited to cool off and started taking the inner cooler off and then turn the car on for a while but it wasn't leaking anymore.
Any sugestions on where it could be leaking from?
I forgot to mention that it's all stock. I was lucky it didn't cougth on fire because I drove for about 10 miles like this.

 

Probably the pulsation damper. It's on the primary fuel rail. If not that, you could have a damaged o-ring on an injector or old cracking fuel lines.

 

probably one of these 2 things.... get that fixed asap...

 

when I got home and after it cool off I had it running for about 5 min. and it didn't leak anymore I even rev it up and nothing. I'm going to have to remove all the intake to check for crack or unplug line?

 

Thanks guys

 

i would fix that before driving around, and risking a fire.

hope you find the source.

 

with the key in the on position but engine off, jumper the yellow two-prong connector on the passenger strut tower. That will pressurize the fuel system and help you find leaks, even if the intake manifold is off.

 

I dont mean to Highjack this thread.. But i notice my fuel Pump always stays on.. If the key is in the on position (not running) the fuel pump just runs. Never shuts off..

 

Thanks for all your help, I think we found the problem, the "O" rings were a little crack so i change all the seals on the injectors.
Thanks arghx I didn't know that this conector will pressurize the system.
It looks that my problem is solve!

 

Someone probably bypassed the AFM safety switch / circuit opening relay and wired the pump directly.

Good. Now it's not a fire hazard .

 

Thanks rotaryrocket88

 

Dont forget about those fuel lines hidden under the uim. Those are not protected by heat wrap and do go bad also..

 

I already check for more leaks and everything seems to be fine now.
Thanks guys
