I have a fuel leak coming from somewhere in the front left side of my engine bay... Upon closer inspection I found that it is leaking all over the inside of the engine bay and around the front left wheel. Although I am not 100% sure, it appears to be leaking from a large metal pipe that has two thin pieces that meet in the middle. I would guess there must be some kind of seal in the middle that could perhaps be leaking? I have read some other posts with similar issues to no avail. I am not very familiar with car engines. Anyway, this problem is leading to very hard starts, taking from 5 to 10 seconds for the engine to start, and it's also causing my engine to idle badly when I stop at lights perhaps... 10% of the time, often so bad that I have to rev my engine to stop it from stalling.
Just want any advice please... Whether it be an easy enough fix for myself, or if I'll need to take it to a mechanic of sorts...
EDIT: Again, on further inspection, I found that the side of the fuel pump appears to be pierced... Every time I press the little metal pump on the top, I see streams of diesel squirt out about 5 inches below the pump press itself. Do I need to replace something or is it as simple as sealing the puncture?
