What I found is if the pump drops into the tank nicely, chances are the small suction line adapter will drop into the receptacle neatly.
If that is misaligned, the pump assembly will be misaligned and the whole shebang won't sit right in the tank.
If its dropped in nicely, and the arrows have lined up on the top of the tank near the fuel lines, and the long bolt drops in nicely and does up with fingers, I'd say you've got it right.
I remember using my inspection camera to double check myself when i did mine - its hard to find, and took some time with lots of pulling the camera out and adjusting the neck before reinserting, attacking from the left hand tank level sender hole. You need a goods mind eye on where to locate it once the pump assembly is in the tank.
