Install & Results
At a glance
- For the Civic/RSX procedure, transfer the OE outlet O-ring spacer and use both supplied O-rings on the new pump outlet. The fuel-sock retainer clip is not reused. Follow the factory service manual for removal of the fuel-pump assembly; it takes priority over conflicting supplemental instructions. The linked guide does not cover the MX-5 installation.
