2016+ Honda Civic 1.5T Plug ‘N Play Flex Fuel Kit

Tools Needed:

13/16” Wrench 12mm Socket Wire Cutters

5/8” Wrench 10mm Socket Ratchet with Extension

9/16” Wrench 8mm Socket Small Flathead Screwdriver

**This kit is designed to be a direct plug n’ play kit, but keep in mind that an engine management system with Flex Fuel capabilities like KTuner or Hondata is required, along with a Flex Fuel Tune.

Begin by inspecting the components of the PRL Flex Fuel Kit, if you have any questions, concerns, or out of place items please contact PRL Motorsports and do not proceed with installation.

Make sure the engine is off and cool. We recommend discharging the existing fuel pressure from the system. Refer to the factory service manual for OEM methods of doing such. A method we use to disable the fuel pump is pulling the Slot 8 fuse in the interior fuse box (consult the underside lid for the correct fuse location), this is a 15amp fuse for reference, then attempt to start the vehicle. The vehicle will most likely run for a brief moment then stall. By doing this the fuel pressure is reduced, be cautious some pressure may still remain in the system.

Remove factory fuel hose bracket 10mm bolts

Remove the white plastic retainer covering the factory fuel lines. There is one located on the top line near the previously removed bracket and bottom line near the valve cover.

Remove the stock fuel line by releasing the clamp with a small flat head screwdriver.

Please Note: that a small amount of fuel will come out of the connection when removing. Use a shop towel to prohibit fuel from going onto other components.

The completely removed fuel line:

Remove the factory fuel line clip

Remove firewall bracket 10mm bolts

Remove the green clip on the upper and lower hard fuel lines

    1. Sorry about this! Unfortunately it appears that all of the image links have been ruined on our blog, so we’ve been going back through and fixing these one-by-one. However, there is a PDF install guide in our product listing if you need!
