Sorry, newbie here. I remember when I used to fix bicycle inner tubes and you could spray soapy water on them and it would bubble at the leak.

Any fun techniques for diagnosing where a fuel leak is coming from?

I have a 1992 300TE and I'm about to go under the car for the first time and see the fuel system, and I am told it is covered with a plastic cover that requires allen wrenches. Any help from you all is welcome.

I'll learn to fix this car one problem at a time, luckily the fuel smell is slight.
