Just put a filter between the UAT and Turbine, then you know the one under the cover is not going to get dirty and you wont have to remove the cover. Problem solved. I think this engine is great and Gives people the ease of switching the turbine from one plane to the other.
Please note that Jetcat says not to put a supplemental filter on the suction side. As the pump is now in the engine you also may have longer fuel tubes from the UAT to the pump; think on using 6mm tube instead of the normal 4mm. Unfortunately i just could make a successful testrun at -2°C in January before putting it in my Futura, but since october the weather didn't allow us to fly on our airfield to test it.
