Greetings... I got my Coupe back from an owner assisted annual. The Fuel flow was normal at that time. It did sit for three months for the winter...and upon starting to fly again, the header tank drains way too fast -- with fuel in the mains. At the annual...the Fuel pump screen was checked and found clean. Cap placed back on and retightened and safety wired. Nothing else really done to affect the system and fuel flow. The cap was tight. Took to Mechanic and he replaced cork gasket in the fuel pump and we checked and there is fuel seemingly coming out the outflow side -- at least some is being pumped. All gas cap vents checked and clear. I'm having a new fuel pump ordered as that seems to be the only thing we can come up with that is problematic. The fuel valve is on (thank you very much :) There is no sign of leakage. I submit to the learned members of the forum... Am I overlooking something? Thanks For any Help...
