There must be washers between the bracket and block causing the misalignment.

Verify the bracket is bent 90*
Verify it bolts fluch to the block.

That I canít answer.... but the pump has been recently installed judging by the grease on the mounting bolts.
One more thing, it might be useful to rotate that hoseclip, maybe itís just the camera angle but it looks mighty close to the engine bed.
