A filter question
Although the UAT will definatly act as some kind of filter I would not rely on it. I had some dodgy fuel which had some sooty black stuff in it which may be this alge stuff people go on about and it found its way past the UAT got trapped in the jetcat supplied filter causing a flame out, when I took the filter apart it looked clean so I tried blowing through the element and it was blocked with VERY small particles of that black stuff.So for that reason I would always use a filter in the engine feed line.
