JSR PRL V3 FK8 Civic Flex Fuel (WiFi) PTFE Line Upgrade

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!

PRL Flex-fuel kit is a great add-on to any FK8 Civic or CV2 Accord 2.0T. However with any rubber lines regardless of the quality and time using ethanol it will degrade. The Oem fuel line is a minimum of 5/16 or 8mm. Unfortunately due to the fittings required to make the Prl Flex-fuel kit cost-effective a 1/4 or 6.35mm hose was used. There have also been some cases in which the line has degraded and broken down. This sends rubber particles through the high-pressure fuel pump. The OEM and Hondata fuel pump can not be disassembled rendering them unusable. Yes, the factory low-pressure fuel line is rubber but on the outside, it has a special layer inside the factory-formed hose and is not a hose you can buy anywhere. This is still not rated for high ethanol co-concentrations.

This Top quality fuel line upgrade will never break down from fuel. The outside is braided stainless steel with nylon. The internal part of the hose is PTFE coated. PTFE 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.
