2017-2021 Honda Civic Type-R FK8 WiFi Ethanol Content Analyzer / Flex Fuel Kit PTFE Line upgrade is here! As we all know none of the filters or fuel lines on the FK8 are ethanol compatible from the Factory. This is why we continue to create new line kits with each evolving flex fuel kit.

Update: As of 01/01/2022, the Lines have been Upgraded to Solid Teflon PTFE core, Steel Braided with Black Raychem Non-Conductive High-Temp Shrink coating. We have the best lines in the industry!


This Top quality fuel line upgrade will never break down from fuel. The outside is braided stainless steel with Braided outer layer for that high performance look. The internal part of the hose is PTFE and is compatible with e85, alcohol, race gas, oil, coolant, and even brake fluid. The 6AN fuel has a rated working pressure of 3000psi. Yes, 3000psi.

Every fitting is billet aluminum with Factory Style quick connects designed to be mounted for a perfect fit to the PRL V1 and V2 Flex Fuel kit. Another nice feature is the solid connection between the factory feed line on the firewall making it easier to install as a solid piece.


NOTE this is only replaces the factory line and does not remove the fittings that came with the V3 kit.
