I have used felt filters in all of my petrol engined airframes in the past with good results, but they do not have a membrane around them to hold fuel around the felt when the level drops, I have noticed that when the fuel level gets low in the petrol engined airframes the engine will start to play up, but does not give up, by using an Orbit clunk this does not happen so it must give a more consistant fuel flow at low levels, this is what made me use one on my turbine, I will keep experimenting and extending the flight envelope to see what happens.
