I use the pleated filter but also just a centralized pickup in a header tank and have never had fuel bubble issues with either . On the other hand , I have seen 2 aircraft lost due to improperly purged UAT's . The bottom line is to assure bubble free fuel and my cheap header tank provides that . I never plan to burn into my header tank . I consider it unusable fuel . After a normal flight I only have a very small amount of air in the header tank that cannot reach the engine with a central pickup .The choice is clear to me .
