Okay so right now i have my s2000 on jackstands while i wait for my wheels to come in, and decided to start the car after not starting it for a week. After starting it i noticed a smell of gasoline.. so i look under my s2 and see a puddle of gas leaking on the floor from the back of the motor. It only leaks when car is running. So was wondering if you guys have any idea to what is causing this? and also how serious this problem could be? and how much i would be spending to get something like this fixed? any advice is greatly appreciated!

 

Trace the fuel lines n check the conditions for cracks n etc.

 

Can you see WHERE it is leaking from? there is the bolt on the top of the fuel rail then a metal hose that goes to a flexible hose to a coupler n a metal hose that runs to the back of the car.

So if it's not leaking at the fuel rail......the flexible hose got cut somehow, the fittings are leaking or the coupler is leaking.

Time to start hunting.

 

You could check the injectors as well, could be leaking from the rubber seals (cheap fix).

 

Yep, mine leaked by the injectors as well. Replaced o-rings, everything is fine ever since. And I've done it myself so no cost, other than the o-rings.
