So my fuel pump just died, outa no where, it didnt stutter it didnt hesitate, when i shut the car off and then tried to start it again i had no pump. So my question is whats the difference between the side tank and the rear tank pump. all i can find on the internet is just Replacement aftermarket pumps but they are the same pumps for the front and the back tanks. i also have no idea what kinda numbers the pump had ( the psi or whatever) and i see that is a big thing with these aftermarket pumps. i dont want a top end pump i just want it to run like it did standard gas guzzling.
