Hi all,
I recently started my 98 es300 and there was a strong smell of gasoline in the cabin. I went outside and looked under the car to find a constant drip from the front engine area near the passenger side front tire. The drip was gasoline, and when i turned the car off the drip slowed to a stop. So any idea what this could be? It only leaks when the car is running so im assuming its when the fuel is being pumped to that area there must be a break in the line? Do you think its safe to drive? Any information is greatly appreciated.
Thanks
