I have the same problem and have been putting up with it for a long time. However, I only have to retry with the key 1-2 times before the engine starts.
My question is ....is there a check valve out there or a kit that can be installed on the fuel line to prevent the fuel backflow to the tank when the engine is shut off?
I can't see dropping the tank to replace the fuel pump at this time.
