Brand new shallow well jet pump, noisy and slow
Were I looking for leaks causing the noise &amp; slow fill issues, I would not expect them to bubble out - they would be leaks on the suction side sucking air in. A shallow-well pump sucks water in (practical limit 27 ft lift from surface of water when pumping - theory might give more than 30 but it's not practical - limited by air pressure and how closely the pump approximates a vacuum) and then spits it out under pressure. 

Static Water level is 8 ft down - how deep is the well, where is the foot valve located? Does the water level drop significantly when pumping?

Here's my best guess as to your root problem:

What is your priming procedure? It appears that you have a check valve on the input, which will prevent priming the pipe from the prime port on the pump - so you'll have to also fill the pipe from the plug in the top of the Tee before the check valve. 

IMHO that check valve is not a great idea, as the foot valve either works or does not work, and the additional check is not helpful, but many pumbing codes are check-valve happy to the point of not helping things.
