Product Description
Acura RSX DC5 & Honda Civic Si EP3 Fuel & Brake Line Holder Brackets
The JBtuned RSX DC5 / Civic Si EP3 Fuel & Brake Line Holder Brackets are designed to securely support aftermarket fuel feed and return lines alongside the vehicle's brake and EVAP/emissions lines underneath the chassis.
The brackets use the factory Honda/Acura underbody mounting studs originally used to retain the OEM line holders, providing a clean and organized way to install a complete aftermarket fuel system without relying on individual P-clamps, self-tapping screws or improvised mounting hardware.
This bracket kit is specifically designed around an 8AN fuel feed, 6AN fuel return and JBtuned 350 Series PTFE fuel hose.

8AN Feed / 6AN Return Configuration
The RSX DC5 / Civic Si EP3 bracket kit is designed for one specific aftermarket fuel-line configuration:
- 8AN Fuel Feed
- 6AN Fuel Return
The bracket openings are designed around the fuel-hose dimensions used with this configuration so the aftermarket lines can be securely supported underneath the vehicle.
This bracket kit is not designed around the factory OEM fuel lines.
Designed for JBtuned 350 Series PTFE Fuel Hose
This bracket configuration is designed around JBtuned 350 Series PTFE fuel hose.
JBtuned 350 Series PTFE hose is compatible with pump gasoline, E85 / ethanol and compatible race fuels.
If you are using a non-JBtuned fuel system or another brand of hose, contact JBtuned before ordering to confirm that the outside diameter of the fuel lines is appropriate for this bracket configuration.
Uses the Factory Underbody Mounting Studs
The JBtuned RSX DC5 / EP3 bracket system installs at the factory underbody mounting locations using the studs originally used to secure the OEM fuel and brake line holders.
When the original mounting studs remain intact and usable, no additional holes need to be drilled into the chassis.
This keeps the aftermarket fuel lines positioned securely against the underbody while making use of mounting points Honda originally provided.
Because RSX and EP3 chassis are now more than twenty years old, inspect the condition of the factory mounting studs before installation.
OEM EVAP / Emissions Line Can Be Retained
Unlike the JBtuned EG/EK/DC bracket system, the RSX DC5 / EP3 brackets include a dedicated position for the factory EVAP/emissions line.
This allows the OEM EVAP line to remain in place when the vehicle retains its factory emissions plumbing.
If the EVAP system has already been removed or reconfigured, the EVAP position in the bracket can simply remain unused.
Brake Line Support
The bracket system organizes the vehicle's brake lines alongside the aftermarket 8AN fuel feed, 6AN fuel return and factory EVAP/emissions line.
Inspect the existing brake lines and their routing before installation. After the brackets are installed, verify that each line is properly seated, supported and routed away from components that could cause heat or abrasion damage.
Chassis-Specific Bracket Design
The kit uses individually designed brackets rather than repeating one universal bracket at every mounting location.
Each bracket is designed around its specific position underneath the RSX DC5 / EP3 chassis so the fuel, brake and EVAP/emissions lines remain organized as they travel underneath the vehicle.
JBtuned has already configured the bracket layout around the intended aftermarket fuel-line system, eliminating the need to assemble a mounting solution from individual clamps and improvised hardware.
What Comes With the Kit
- Three JBtuned underbody fuel and brake line holder brackets
- Black ABS construction
Compatible With JBtuned Complete Fuel Systems
These brackets are designed as an underbody mounting solution for compatible JBtuned RSX DC5 and Honda Civic Si EP3 complete fuel-system installations.
They replace the original plastic fuel-line holders with a bracket system designed around the larger aftermarket 8AN feed and 6AN return while retaining the factory brake-line routing and, when desired, the OEM EVAP/emissions line.

Installation Notes
- Remove the original underbody line holders and install the JBtuned brackets using the existing factory mounting studs.
- Inspect the original mounting studs, brake lines, EVAP line, fuel-line routing and surrounding underbody components before installation.
- The brackets are designed for an 8AN aftermarket fuel feed and 6AN aftermarket fuel return using JBtuned 350 Series PTFE hose.
- The factory OEM fuel-line configuration is not supported.
- The factory EVAP/emissions line may be retained because the brackets include a dedicated position for that line.
- All fuel and brake lines must be securely mounted and routed away from exhaust heat, moving components, sharp edges and areas where road debris or abrasion could damage them.
Questions About Fitment?
If you are using a non-JBtuned fuel system or are unsure whether your fuel hose will fit this bracket configuration, contact JBtuned with your vehicle, year, fuel-line sizes and fuel-hose type before ordering.
