Ford Mustang Fuel Injection Conversion

Filed Under (Ford) by admin on 04-05-2012

Download These instructions will provide the basic and necessary information to allow a carbureted 302 to be converted to SEFI Fuel Injection. There are several different types of fuel injection conversions available, however, this instruction will concentrate on the High Output, MASS-AIR setups found on the 92-93 Ford Mustangs. There are two main advantages to using this type of setup. The first advantage is that the computer in the MASS-AIR system will automatically compensate for any engine modifications that have been done prior to the installation of the fuel injection system. The second advantage is that fuel is sent to each cylinder individually only during the appropriate firing cycle, meaning that fuel is sent sequentially to each cylinder only when the spark plug is ready to fire. This makes for an extremely efficient firing cycle . SEFI stands for Sequential Electronic Fuel Injection. This system is complex to be sure, therefore, this instruction is going to skip all the technical mumbo-jumbo, and focus on the bare essentials to install this system properly.… Read More
