    "FUEL PUMP

    You will also need to add in a inline fuel pump. For 500hp (not whp) cars, a walbro 255lph inline pump will be plenty. For those looking for more, a bosch 044 pump will support around 700hp. There is a problem with most aftermarket intake pumps, they often starve for gas when the tank is less than 1/4 tank. So its best and cheapest to just add in a inline pump. Also keep in mind that after you get to around 500whp, you will also be forced to increase the size of the fuel line and also even do a surge tank so you dont starve for fuel."
