The PRL Flex-fuel kit is a great add-on to any Fk8. However with any rubber lines regardless of quality with enough time and 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 to make. This is still not rated for high ethanol concentrations.
This Top quality fuel line upgrade will never break down from fuel. The outside is braided Stainless Steel with Nylon on top. The internal part of the hose is PTFE. PTFE is compatible with e85, alcohol fuels, gas, race gas, oil, coolant, and even brake fluid. The 6AN fuel has a rated working pressure of over 3000psi. Yes, 3000psi. So pretty much no matter what you put in it or spill on it, it will NOT degrade.
Every fitting is billet with Factory Style quick connects designed to be mounted for a perfect to the Prl Flex Fuel kit. One other nice feature is the solid connection between the factory feed line on the firewall is now easier to install and a solid piece. The factory feed line has support again increasing longevity. A bonus is it makes servicing or removal of the Prl Flex-fuel kit easier. You are no longer forced to try and stretch or bend the factory line and small rubber line included.
