Hey Kris, Looks good mate. Just need more pics!
Are you sure the pump is 'hanging low' enough in the basket? It looks to me like the inlet won't sit on the bottom of the tank. You have to mount it in the tank and push it down all the way, then lift it 3mm or so so the inlet is not jammed against the bottom too hard so the fuel flow gets restricted.
If you don't you'll run out of fuel pressure even though the tank is still 1/3 or less full... don't ask me how I know, lol!
