I currently have a walbro 255 lph hp pump. Its too loud for my taste so I was looking at a quiet replacement. So I'll probably upgrade to this HFP 320LPH Fuel Pump Ford Mustang GT 5.0/4.6 1986 - 1997 How do I go about upgrading the factory wiring? Ive found this Fuel Pump Hot Wire Kit but not sure how to install it? Anyone have experience with the hot wire kit? Or other ways to wire pumps that require more voltage?
