Is my 300E going to blow up?

After I garage my car in the evening and step back into the shop I smell fuel and it's strong enough to warrent a post to see if any one has any ideas. I suspect it is coming from under the bonnet however one time we smelled fuel inside the cabin like when you flood a car but the car was not flooded it was running. This was a couple of months ago and never has happened again. Car starts, idels, and runs great. Any help on where to start would be greatly appreciated.

Thank you

I would start by visually tracing the fuel lines from the fuel tank to injectors to see if you can spot any leaks.

You said it happened about a month ago and since then, nothing.....
Could it be that you simply over-filled your gas tank at this time.?

Sorry Jackd the fuel smell in the "cabin" happened only once. However the smell outside the car is persistant.
Ali, the fuel lines from the rear on up are dry as a bone. When I was searching for my coolant leak a few months back we had a chance to inspect the entire under side and for a 13 yr-old car everything "looked" like it was in pretty good shape. This evening I think I may have found the problem, attached to the (excuse my ignorance) brain looking thing where all the fuel injector lines come togeather (fuel distributor?) there is a black box (Bosch) on the fire-wall side.
On the top center of this electrical box there is a hole. (like a weep hole?). This is where the fuel is comming out. I wiped it clean, it was pretty wet, and within a few minutes fuel was seeping out this hole again. Ok, so why is there a hole here and why is it leaking fuel, and what do I do to fix it?
You guys are great, thank you in advance!

Question That is the EHA!

You have to replace it. Two screws and it is out,put a new one in. Not too expensive from Fastlane.
