AEROMOTIVE Part # 13106
AND Part # 13107 INSTALLATION
INSTRUCTIONS
CAUTION:
Installation of this product requires detailed knowledge of automotive
systems and repair procedures. We recommend that this installation be carried
out by a qualified automotive technician.
Installation of this product requires handling of gasoline. Ensure you are
working in a well ventilated area with an approved fire extinguisher nearby.
Extinguish all open flames, prohibit smoking and eliminate all sources of ignition
in the area of the vehicle before proceeding with the installation.
When installing this product, wear eye goggles and other safety apparel as
needed to protect yourself from debris and sprayed gasoline.
WARNING!
The fuel system is under pressure. Do not open the fuel system until the
pressure has been relieved. Refer to the appropriate vehicle service manual for
the procedure and precautions for relieving the fuel system pressure.
NOTE: Testing the enclosed regulator by applying air pressure or vacuum to the vacuum port with a
hand-held pump will yield poor results, due to the slight air leakage through the adjustment screw
threads. This minute leakage, which is typical of all adjustable fuel pressure regulators, does not, in any
way, affect the performance of the regulator.
NOTE: A fuel pressure gauge will be required to set the regulated pressure once you new Aeromotive
regulator is installed. It is recommended that you check the base fuel pressure, as set by the factory
regulator, BEFORE you remove it. To determine base fuel pressure, connect the appropriate gauge to
the factory fuel pressure test port, disconnect the vacuum line at the regulator and plug it, start the engine
and observe the gauge. Note the gauge reading for future reference.
Aeromotive system components are not legal for sale or use on emission controlled motor vehicles.
The following steps are typical of most installations:
1. Allow the engine to cool, disconnect the negative battery cable and relieve the fuel system pressure.
2. Remove any cosmetic covers necessary to allow access to the fuel pressure regulator. On most
models, the regulator is located on the fuel crossover tube between the fuel rails or on the passenger
side fuel rail. Some models require removal of the fuel rail(s) to install this product. If your vehicle
requires removal of the fuel rail(s), refer to the appropriate vehicle service manual for the procedure
for doing so.
3. Remove the vacuum line from top of OEM regulator.
