Some of the pictures and notes from the video are presented here, but please see the video for the installation instructions and tuning guide. Also please see the fuel injectors removal instructions as the process is very similar since the fuel rail must be removed.
Here is the strut tower brace – remove the two 14mm bolts and two 14mm nuts.
Remove the four 12mm bolts holding on the throttle body inlet.
Remove the two 10mm bolts and the two 12mm bolts holding on the throttle body bracket.
Remove the four 12mm bolts holding on the throttle body.
Then move the throttle body out of the way without removing the coolant lines. If you would like to remove the coolant lines, it’s not a big deal, just be prepared for a small amount of coolant to leak out, and replace that coolant when installation is complete.
Remove the 12mm bolt supporting the EGR assembly, and disconnect the EGR electrical connection.
Remove the two 12mm bolts holding the EGR assembly to the intake manifold. See arrows on right of picture.
Remove the Allen bolts holding the EGR assembly onto the head. The EGR assembly can now be removed.
Remove the two 12mm bolts holding on the cold start injector pipe. There are two washers per bolt.
After the cold start injector is removed, unbolt the wiring harness from the intake manifold – two 10mm bolts.
Unbolt the three bolts holding the fuel rail in place. Pull on the wiring harness to move it out of the way, and then lift out the fuel rail.
Remove the 10mm bold holding the fuel inlet pipe in place, then remove the stock fuel pressure regulator.
Stock regulator removed:
Install the 90 degree fitting into the fuel rail where the stock regulator once was.
Connect one of the three barbed fittings included in the kit. There is no reason to use any teflon tape on this connection.
Attach the fuel hose and hose clamp.
Assemble the Aeromotive fuel pressure regulator with the fittings and fuel pressure gauge included in the LoveHorsepower kit.
Drill two mounting holes in the firewall at an appropriate location. Be sure that the top of the regulator will clear the hood when closed. Check that you have clearance to loosen the adjusting screw on top of the regulator – ie make sure that when the screw is full loosened, you still have clearance to close the hood. Use the fittings and hose clamps included with the kit to attach the fuel return line. Please use teflon tape on the gold colored fittings. All other fittings (blue) do not require any sealant.
