Troubleshooting and Problem Solving

Common Issues After Installation

• [Fuel smell]: Loose AN fitting or fuel line connection.
• [Gauge reads zero]: Fuel pump not running or gauge port not sealed.
• [Unstable pressure]: Air in line or regulator setting not locked.
• [External leak]: Fitting flare not fully seated.

Error Code Solutions

• [No product specific DTC]: Scan vehicle and inspect fuel pressure first.
• [Lean fuel condition]: Check pressure setting, hose routing, and leaks.
• [Rich fuel condition]: Reduce pressure setting and verify return line flow.

How to Reset Check Engine Light After Installation

• Repair leaks and confirm stable fuel pressure.
• Use an OBD2 scan tool to clear stored codes.
• Start the engine and monitor idle condition.
• Road test and rescan for returning codes.

What to Do If Your Vehicle Loses Power After Installation

• Stop driving if fuel odor or leakage is present.
• Verify the regulator pressure setting with the gauge.
• Inspect AN6 hose routing for kinks or restrictions.
• Confirm inlet and return ports are connected correctly.
• Contact service@egrperformance.com for support.
