Gas empty TSB 10-21-3 did it actually fix the trouble?

I just did the first fill up of my gas tank after I saw my gas gauge go from one quarter left to empty in several seconds. I filled the tank and it took only 9.6 gallons!

I found out that there is a Ford TSB on this problem-TSB10-21-3 that was dated 101910 .

My GT was made on 111810-almost a month after the issuance of this TSB. It seems that either Ford built my car with a known defective fuel module/pump FPM or that the replacement FPM fuel module/pumps are defective.

This TSB says to replace the FPM with part number BR3Z-9H307-B .

Has anyone had this FPM replaced for this problem and has the problem recurred?

A guy over on allfordmustangs had one replaced under the TSB and then his fuel pump crapped out and they replaced that to get a final fix.
