Features & Product Details

PERRIN High-Flow Fuel Rails incorporate large inside diameter channels for maximum fuel flow. This allows for cars to run 800 WHP without inconsistent fuel flow to each cylinder. We include custom made -6 barbed fittings with O-rings to ensure a proper connection to the hose. These fittings are removable allowing for easy customization of aftermarket fuel lines.

The equal flowing nature of PERRIN fuel rails allow your high powered Subaru to make more power, safer. A must have for any car looking to exceed 400 horsepower.

PERRIN High-Flow Fuel Rails split incoming fuel for equal fuel distribution, pressure, and more consistent air fuel ratio between all cylinders. The stock fuel rails route the fuel through the engine bay sequentially providing each injector with fuel. In modified Subarus, this drastically reduces fuel delivery to the last injector in line.

The PERRIN fuel rails and distribution block are precision CNC machined from 6061 billet aluminum. Each -6 Barbed Fitting is removable from the rails and distribution block allowing for easy customization of aftermarket fuel lines.

All PERRIN High-Flow Fuel Rails come with built-in phenolic spacers. The spacers fitted to fuel rails and junction blocks sit between these and the engine, insulating it from heat. This keeps fuel closer to its normal ambient temperature. In contrast, without these spacers, you can see fuel temperatures rise far more than 30 degrees above ambient.

PERRIN fuel rails feature large 3/8” inside diameter fuel injection hose which provides higher flow rate than competitive systems. This hose is large enough to support 800+ WHP. Included hose is a DOT approved, rubber fuel injection hose with proper liners for zero emissions. A byproduct of the hose being constructed of rubber is that it helps dampen the fuel against pressure waves and, in turn, creates a smoother and more constant fuel pressure.

Disappointment indeed  10 months ago
Subiecam
Bought this kit because it seemed to have everything needed for 500 bucks. I️ wish I wouldn’t have opened it up and ruined the ability to return it. The fittings are crap especially for a fuel system!! Wasn’t happy with the way it looked or performed. You’d be better off buying just rails then getting your hoses and fitting so you don’t have to do it twice like me 👍

  • Q: Fitment options  RMS dude2 years ago

    Will any top feed injector work with this kit? I'm planning on getting the Cobb Flex Fuel pack and need to know if there will or could be any issues with these kits meshing together

      A:  This kit will work best with Injector Dynamics injectors. There will be no fitment issues with the Cobb Flex Fuel Pack.
