Features & Product Details

RallySport Direct proudly carries COBB Tuning products to provide the die-hard car enthusiast with a quality product that is a result of decades of engineering, expertise, and careful manufacturing methods that you can always be satisfied with. 

On this page, you will see that COBB Tuning has put together an effective package for those of you looking to upgrade your fuel system. This is the COBB Tuning Fuel Rail and Line Kit Package. 

The Fuel Rail Line will work with the COBB Flex Fuel Kit. E85 is becoming more commonplace, which means you will need to have all the right fuel components to successfully employ this fuel. All the lines are pre-assembled with double swivel sport crimp style hose ends and will come ready for the installation. Stainless reinforced PTFE line with black covering has a 3" minimum bend radius which will allow for straightforward installation as long as its used as intended. These are super durable lines with a 2500 psi rated operating pressure and a 10000 psi burst pressure. 

The fuel lines will be combined with the COBB Tuning Fuel Rails.  These rails have been constructed from 6061 Billet aluminum materials and feature black anodizing with a laser etched COBB logo. Each rail will have a -8 AN to a -6AN adapter that is pre-installed to makes these rails ready for the installation. 

Whether if you are planning on a big HP build, or if you need a fuel system that can sustain the perils of E85, then you will be satisfied with the performance of this kit.

Received quickly from RSD as usual. Lines are good quality, stiff lines but if installed correctly they connect exactly Where they're suppose to go without much play which is good imo for .engine bays. Thank u rallysportdirect!

  • Q: Function  Slowbaru_sty2 years ago

    Does this change the fuel deliever from series to parallel?
    • 1 of 1 people found the following answer helpful

      A:  This kit would not directly change the fuel delivery to a parallel system, but you can use this kit to route everything properly to switch your fuel system to parallel.
