• Hard starting caused by inconsistent fuel delivery
• Rich or lean running conditions related to pressure control
• Fuel smell or drivability issues tied to regulator wear
• Loss of smooth throttle response in Honda Civic and Honda CRX fuel systems

Installation Notes

Verify the vehicle uses a gas fuel system and confirm the 43 psi specification before installation. Match the straight nipple orientation and inspect fuel lines, seals, and related injection components for wear during service.
