The Karcepts K-Swap Fuel Line Kit for K-Series powered 88-00 Civics & 94-01 Integras provides the SOLUTION to properly fuel a K-Series engine when installed into an EF, EG, EK, or DC2 chassis while:
Option #1: Clean & Simple 2 Line Setup
This fuel line kit mounts the fuel pressure regulator (FPR) on the end of the fuel rail, creating a clean, in and out, 2 line setup; eliminating the need to mount the FPR on the shock tower. However, when the FPR is mounted on the end of the fuel rail, it will interfere with the large and bulky OEM 2002-2006 RSX-S and 2002-2005 Civic Si throttle cable brackets. To avoid this interference issue, you must use either a Karcepts Cruise Control Delete Kit (for RSX-S and Civic Si cruise control style throttle bodies), a Karcepts Throttle Cable Bracket (for aftermarket non-cruise control style throttle bodies), or an OEM JDM DC5 Type R or JDM EP3 Type R non-cruise control throttle body and bracket.
Use Karcepts P/N: KFL01 for EF, EG, EK w/ EG or DC2 crossmember, and DC2
Use Karcepts P/N: KFL02 for EK w/ EK crossmember

Option #2: Standard 3 Line Setup
This fuel line kit is the standard routing typically seen on most K-Swaps. It will require mounting the fuel pressure regulator (FPR) on the left side shock tower. Typically, most of the chassis have M6 tapped holes on the side of the shock towers, so mounting in this location should not be too difficult. This is the setup to choose if using an OEM 2002-2006 RSX-S or 2002-2005 Civic Si throttle body with the factory throttle cable bracket or any throttle body setup not described as working with Option #1. If uncertain on throttle body/throttle cable plans, this fuel line kit may be the best option to choose as it guarantees no fitment issues.
Use Karcepts P/N: KFL03 for EF, EG, EK w/ EG or DC2 crossmember, and DC2
Use Karcepts P/N: KFL04 for EK w/ EK crossmember
