the problem is, the most recent fuel pump they sell, doesnt have that style inlet filter shown at the bottom of that article. it has a 'sock' type filter that hangs off the side. the people who used that other- older model replacement pump, dont seem to have the 3rd gear stutter.
as a mechanical engineer myself, i truly believe this problem is directly related to the newest style pump Ford sells. if i had to guess, id say the pumps natural frequency is oscillating against another freq. the car produces in that rpm range in third gear, causing the fuel injection fluctuation. either that, or injection timing and flow rate needs to be modified for this pump.
