General Installation Guidelines:

1. Preparation: Ensure the vehicle's fuel system is completely depressurized and the battery is disconnected. Gather all necessary tools and fittings (ORB-06 fittings are required for inlet/outlet).
2. Mounting: Select a suitable location for the regulator, preferably close to the carburetor, ensuring it is securely mounted using the provided bracket. The location should be away from heat sources and moving parts.
3. Fuel Line Connections: Connect the fuel supply line from the pump to the inlet port (typically the bottom port). Connect the outlet port(s) to the carburetor(s). The regulator features two outlet ports for versatility; block off any unused ports with appropriate plugs.
4. Gauge Installation: Install a fuel pressure gauge into the dedicated 1/8" NPT gauge port to monitor pressure.
5. Leak Check: After all connections are made, re-connect the battery and prime the fuel system. Carefully inspect all connections for any signs of fuel leaks before starting the engine.
6. Initial Adjustment: With the engine running, adjust the regulator to the desired fuel pressure within the 5-10 PSI range.

• Cleanliness: Keep the exterior of the regulator clean and free from dirt, debris, or corrosive substances.
• Component Integrity: Inspect the mounting bracket and the regulator body for any signs of damage, corrosion, or wear.

Troubleshooting

If you experience issues with your Aeromotive 13201 fuel pressure regulator, consider the following common troubleshooting steps:

• Unstable or Fluctuating Pressure:
  • Check for air in the fuel system.
  • Ensure the fuel pump is providing adequate and consistent flow.
  • Verify all connections are tight and free of leaks.
  • Inspect the fuel filter for clogs.
• Pressure Too High/Low (and not adjustable):
  • Confirm the gauge is accurate.
  • Ensure the adjustment screw is not stripped or damaged.
  • Check for obstructions in the fuel lines or regulator ports.
  • Verify the regulator is correctly plumbed (inlet/outlet).
• Fuel Leaks:
  • Immediately shut down the engine and depressurize the fuel system.
  • Inspect all fittings (ORB-06) for proper tightness and sealing.
  • Check O-rings and seals for damage or improper seating.
  • Ensure fuel lines are not cracked or chafed.

If issues persist after troubleshooting, contact Aeromotive customer support or consult a qualified automotive professional.
