Just curious, but why would you go to a smaller size line if you think your having a fuel delivery problem?
Are you trying to cause a restriction to raise pressure?
In theory it should work.
It very well may be that your 280 pump is not capable of flowing enough volume of fuel thru the lines to maintian 7.5 PSI while the needle is off the seat.
I agree, get a 'better' higher volume pump.
