fuel

The one's I've seen have been a black gungy sort of thing with long bits hanging off the edges. Sort of like RTV sealant that has been exposed to petrol, sort of jelly like.

Hi Barry

You normally wont see it in your fuel unless really bad where it will make the fuel a brown colour.
You will normally notice that you have it due to a brown slime on your filter element. If you filter is a spin on, cut it open to see if this is the case.
If you find you have algae in the fuel the easiest way to get rid of it is by adding a fuel conditioner to the tank, but be prepared to change the fuel filter a few times.

The trouble is is that it very difficult to get rid of the algae once you have it. Even the fuel conditioners such as chemtech dont get rid of it altogether although they will prevent it from occurring.
Once you have it your only option is to frequently use the treatment.
