Fuel Delivery problems of the 2001 GMC Sierra

I recently purchased a 2001 GMC Sierra,the first tank of fuel that was put in the fuel gage jumps from full to empty, it has continued to do this until the current date, I have several people I have talked to in my area with same vehicle with different years 1999-2002, experiencing same problem, was told by mechanics that it is the fuel sending unit, have talked to people who's vehicle"s have shut down because of it, should be a recall on this problem,very unsafe!.
