This part cross-references Honda (e.g., 16015S6M930) for the same application. Search terms such as fuel injection pressure regulator for 2002-2005 Honda Civic, returnless fuel regulator for Acura RSX, and gas fuel pressure regulator for Honda Insight align with this application coverage.
Common Problems This Part Can Address
- Fuel pressure that is too high or too low
- Hard starting caused by unstable fuel delivery
- Rough idle related to inconsistent injector pressure
- Fuel system performance issues in returnless setups
- Check engine concerns tied to fuel pressure regulation
Installation Notes and Tips
Verify the vehicle uses a gas returnless fuel system before installation. Confirm the inlet and outlet layout matches the original regulator and inspect surrounding fuel lines and seals for wear before reassembly. Because this is an adjustable regulator, set fuel pressure to the vehicle specification after installation and verify operation with a proper fuel pressure test.
Quality Assurance
Standard Ignition supplies replacement fuel system components for service applications, and PR512 is a new part built to meet the needs of the listed Acura and Honda fitments.
