What years for Mustang, that have have an access panel through the floor, so you don't have to drop the gas tank to replace the fuel pump?

 

I believe that from the 05 to mow they are under back seat drivers side , I have an 07 gt/cs & have had it out a few times because the sock picks up so much eww it stops to flow , I clean it & it's ok. I did buy a new pump but it failed in 2 months so I cleaned the original & going good.
