JSR PRL FC1/FC3 Civic SI FK7 PTFE Flex Fuel Line Upgrade Civic 2016-2021

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 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.
