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 mount JBtuned or compatible aftermarket fuel feed and return lines alongside the vehicle's brake and EVAP/emissions lines underneath the chassis.
Designed around the factory Honda/Acura underbody mounting locations, these brackets use the OEM mounting studs originally used to retain the factory line holders.
This provides a clean, organized way to mount a complete aftermarket fuel system without relying on individual P-clamps, self-tapping screws, or improvised mounting methods.
This bracket kit is specifically designed around an 8AN fuel feed and 6AN fuel return using JBtuned 350 Series PTFE fuel hose.

8AN Feed / 6AN Return Configuration
The RSX DC5 / Civic Si EP3 bracket kit is currently designed for one fuel-line configuration:
- 8AN Fuel Feed
- 6AN Fuel Return
The brackets are designed around the outside diameter of the fuel hose used with this configuration so the lines can be properly supported underneath the vehicle.
This bracket kit is not designed around the factory OEM fuel-line configuration.
Designed for JBtuned 350 Series PTFE Fuel Hose
This bracket configuration is designed around JBtuned 350 Series PTFE fuel hose.
350 Series PTFE fuel hose can be used with conventional pump gasoline, E85, ethanol-based fuels, and race fuels.
If you are using a non-JBtuned fuel system or a different brand of hose, contact JBtuned before ordering to confirm that the outside diameter of your fuel lines is appropriate for the bracket configuration.
Uses the Factory Underbody Mounting Studs
The JBtuned RSX DC5 / EP3 bracket system is designed to install using the factory underbody studs originally used to secure the OEM fuel and brake line holders.
When the original mounting studs are intact, the brackets install at the factory mounting locations without requiring additional holes to be drilled into the chassis.
This keeps the aftermarket fuel lines securely positioned against the underbody while making use of mounting points Honda originally provided.
Because these vehicles are now more than twenty years old, inspect the condition of the factory mounting studs before installation.
OEM EVAP / Emissions Line Can Be Retained
The JBtuned RSX DC5 / EP3 brackets include a dedicated position for the factory EVAP/emissions line.
This allows the OEM EVAP line to remain in place if you choose to retain the factory emissions plumbing.
If your vehicle's EVAP system has already been removed or reconfigured, the EVAP position in the bracket can simply remain unused.
Brake Line Compatibility
The bracket system organizes the vehicle's brake lines alongside the aftermarket 8AN fuel feed, 6AN fuel return, and factory EVAP line.
Inspect the existing brake lines and their routing before installation and make sure all lines are properly seated and secured after the brackets are installed.
Chassis-Specific Bracket Design
The kit uses individually designed brackets rather than one universal bracket repeated at every mounting location.
Each bracket is designed around its position underneath the chassis to provide a clean fit while keeping the fuel, brake, and EVAP/emissions lines organized.
JBtuned has already engineered the bracket configuration around the intended fuel-line layout so the customer does not have to piece together individual clamps and mounting hardware to secure the system.

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.
They are not intended to retain the factory OEM fuel-line configuration.
The factory EVAP/emissions line may be retained because the brackets include a dedicated position for that line.
All fuel and brake lines should be securely mounted and routed away from exhaust heat, moving components, sharp edges, and areas where road debris or abrasion could damage them.
Complete Your JBtuned Fuel System
These brackets are designed as a direct underbody mounting solution for compatible JBtuned RSX DC5 and Civic Si EP3 complete fuel-system installations.
They replace the original plastic fuel-line holders with a bracket system designed around the larger 8AN feed and 6AN return used with these aftermarket fuel systems.
