99 mustang gt here. im having a problem accelerating once my gas tank gets below a quarter tank... do i need a fuel pump or do one of you guys know what the problem may be. once my gas is that low the car starts bogging even though i know im in the right gear and im giving enough gas. this only seems to happen when my tank is at that position. help asap please. thanks in advance.

 

check the fuel pump and injectors. my buds injectors got clogged and wow it sucked. but an upgraded fuel pump never hurts.
