Now August 9 th 2007. No problem with fuel gauge since improved sender boards were installed. Probably they are the 2007 boards mentioned in other emails and I listed their part numbers above. Don't think Chevron additives are going to do anything since that is all my Mustang has had.

 

I am looking to replace the sending units in the tank myself, don't want to have to go through taking crap off the car for the fuel gauge problem. I heard the sending units can be accessed through the floor under the back seat in that correct?

 

Pretty sure that is correct since my left rear seat belt was caught under the seat and I asked them if they removed the rear seat to replace the boards and they replied "yes". I was wondering myself what I am going to do after April 2008 when warrantee goes out.
