Fuelmiser pump FPE284 is totally different from the original intank one.
I'm not sure why you had to use Fuelmiser pump FPE284, instead of replacing it with an original one.

I can't understand why it should leak fuel, unless the O ring seal of the sender unit assembly was damaged badly enough.
It's not that easy to damage it.

Another thing you need to consider is that the fuel pressure of the Fuelmiser pump FPE284. It may be too high.
The AC Delco parts listings had the original pump listed with a photo that was a direct match. Couldn't find a Delco pump available but the Delco book cross referenced the Fuelmiser pump number which was available, so I ordered the fuelmiser pump.
Didn't even bother enquiring about genuine Nissan parts- pricing is normally calculated on an additional 300% sucker surcharge.
Didn't expect the O ring to leak for the reasons you mentioned, but all hoses are secure and the fuel leak is coming from the O ring area - Impossible to see with the tank in place in the car.
