Remember one think wgen buying a part for fuel it has a specific part number cross check it online on toyota diy site and check for the price tag too mentioned there.
Even 1994 corolla 1.5 which is launched here in pakistan fuel pump costs around 21000pkr for genuine. Same like new corolla sold here fuelpump starts from 45000pkr and same is the list for all vehicles.
As per your experince about 9k cost pump its on first hand make some doubts about it either its smuggled or its counterfeit.
Most of the time we do get our hands on smuggled brand new parts of toyotas.
For hamza younas auto this gesture is hinted toward counterfeit part so always cross check from mehran autos about the part and price before buying.
Window shoping always helps if the survey is being done properly
