Not that I'm fixated about this....well maybe....., but can we have a sticky that says something along the line of:
"Fungus, fungus. Not algae. Algae requires light to survive (can be a plant or a symbiotic creature that has photosynthetic cells). As far as I know, no light reaches the fuel unless you have a clear acrylic hood and a clear pre-filter."
I started making some corrections, and realized I was turning into a spammer because there are so many threads that refer to algae in one's fuel system.

Also,

No More Algae
...okay now I'm just being silly....okay maybe I'm doubling the silly, but still, I feel like I need to correct people every time as it is one of the few things I know about my car with confidence
