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.

The fuel system may be under pressure. Do not open the fuel system until any pressure
has been relieved. Refer to the appropriate vehicle service manual for the procedure and
precautions for relieving the fuel system pressure.

The enclosed Aeromotive regulator utilizes two o-ring sealed AN-10 style inlet ports and four o­ring sealed AN-6 style outlet ports; these regulator ports are NOT PIPE THREAD
THREAD SEALANT.

Performance Specifications: Model 13203

Inlet Fuel Pressure 15 - 45 psi
Outlet Fuel Pressure, adjustable 7 - 11 psi

Aeromotive system components are not legal for sale or use on emission controlled motor vehicles.

The following steps are typical of most installations:

1. Once the engine has been allowed to cool, disconnect the negative battery cable and relieve the

fuel system pressure.

2. Place shop towels around the regulator to catch any gasoline that is spilled during this step of the

installation. Remove any regulator mounting hardware and connecting fuel lines, then carefully
remove the regulator.

3. Find a suitable place in the vehicle’s engine compartment to mount the Aeromotive regulator. Using

the supplied mounting bracket as a template, mark the bracket mounting holes and drill to accept a
#10 screw.

4. With the bracket attached to the regulator, mount the bracket and regulator to the vehicle using two

#10 screws, nuts and lock washers.

5. Attach the fuel supply line(s) to the regulator using AN-10 style fittings and o-rings. If only one fuel

supply line is used, install an AN-10 style plug and o-ring into the second regulator inlet port.

INSTALLATION INSTRUCTIONS

WARNING!

and utilize NO

6. Attach the fuel supply line(s) to the carburetor(s) using AN-06 style fittings and o-rings. Install AN-

06 style plugs and o-rings into the outlet ports not used.

7. Tighten all connections.

8. Once the regulator is installed, attach a suitable fuel pressure gauge to the 1/8 NPT port on the fuel

pressure regulator.

9. Ensure that any spilled gasoline and any gasoline soaked shop towels are cleaned up and

removed from the vicinity of the vehicle!

10. Reconnect the battery and turn the fuel pump ON WITHOUT starting the car. After several

seconds, check the fuel pressure. If there is no fuel pressure, turn the fuel pump OFF, wait one
minute, return the fuel pump ON, and recheck the fuel pressure. Repeat this OFF and ON
procedure until the fuel pressure gauge registers fuel pressure.

11. With the fuel pressure gauge registering fuel system pressure, check for fuel leaks from and

around the Aeromotive regulator and all fuel lines and connections near the regulator! If any
fuel leaks are found, turn the fuel pump OFF, remove any spilled fuel and repair the leak
before proceeding!

12. Once the fuel pressure gauge registers fuel system pressure and there are no fuel leaks, start the

engine and adjust the regulator to the desired fuel pressure. Turning the adjustment screw
clockwise will increase fuel pressure.

13. Once the desired fuel pressure is achieved, tighten the regulator adjustment jam nut.

14. If you do not want to keep the fuel pressure gauge on the vehicle, relieve the fuel system pressure

as instructed in the appropriate vehicle service manual. Remove the fuel pressure gauge and
reinstall the 1/8 NPT pipe plug into the regulator gauge port, using thread sealant..

15. Test drive the car to insure proper operation and re-check the fuel system for leaks. If any leaks

are found, immediately shut off the engine and repair the leak(s)!
