Infiniti Q45 Lack of power on acceleration due to fuel pump issue

I found out that my fuel pump was faulty in my 1994 Q45t a few years ago. I took it in for service due to the lack of power on acceleration AND the fact that it would not simply glide or float on the freeway anymore when I eased up on the gas pedal, instead it would rapidly slow down almost as if I were applying my foot on the brakes. was absolutely flabbergasted when our mechanic told me how much it would cost to replace it. EVEN IF I bought the fuel pump from Auto Zone myself, he would be charging me $575 JUST FOR THE LABOR because the repair involves dismantling the entire gas tank and opening it up since the fuel pump is housed INSIDE THE FUEL TANK!! - Visitor
