so i wanna know if it would be possible to go from an intank electic fuel pump to a vaccum mount under hood type for efi motor...

Nope
EFI require's consistent specific fuel pressure's to start and operate properly.

You May be able to convert to an external inline electric pump, but that's the best you can do with EFI.
