Added bonus is this pump's readily available at any local auto parts store. After installing the new pump, the next step was wiring in the fuel pump controller for the EZ-EFI system.
With the tank down, use a hammer and beat/fold this lip of sheetmetal (left from factory assembly) down till it's flush with the frame rail, as in the photo.
This lip always catches the filler neck, making it impossible to angle the tank downwards enough to remove it without having to disconnect the rear suspension and lower the rear end for clearance. Even though our RS came with fuel injection from the factory, it was the lower pressure TBI system (pump on the right).
If you're running a carb equipped engine that already has four-barrel linkages, you won't even have to change those to work with the FAST throttle body. The control harness for the EZ-EFI system comes fully labeled, so you know instantly where all the connections go with no mystery.
While not fully plug-and-play, EZ-EFI has most of the work already done for you, with only some simple wiring mods on the car's factory harness necessary.
All you have to do is drive the car around while the computer does the work. The system uses a throttle body equipped with fuel injectors and sensors, with a Holley base flange.
This gives the EZ-EFI system an almost universal application, as long as your intake can accept a standard Holley flange. The first step is clearing away all the factory TBI junk, then pulling the manifold.
It has a simple, three-wire hook up that'll interface with our EZ-EFI system for power, and provide plenty of spark energy to let our small-block make the most of the new fuel system. The FAST throttle body is pretty much self contained, with all the EFI sensors and fuel injectors already bolted on.
It simply drops onto the intake and gets bolted down.
Using a high-pressure, fuel injector-equipped four-barrel throttle body, EZ-EFI is FAST's user friendly system that requires no laptop tuning, no complicated tuning software, and can be installed on almost any engine as long as the intake will accept the throttle body. The starting point for our install is FAST's (Fuel Air Spark Technology) EZ-EFI unit.
