I think you are barking up the wrong tree.
I think your pump is shot or partially blocked...but who am I to argue.
It is not possible to post files on this forum & rightly so. If you want a schematic that bad you would have to risk posting an e-mail address. Personally speaking I wouldn't even consider doing it...being bombarded by spammers or other cranks certainly does not appeal to me.
