This kit is designed for anyone that's reconfigured their fuel system to support a -8AN supply and return line to the rail. This is a common setup for very-high horsepower k-swapped vehicles. Other vehicles that come standard with a K-Series motor are sometimes reconfigured to a -8AN return setup when running very high horsepower applications, particularly for turbocharged vehicles. The fuel lines are not included with this kit. When configuring the kit, you'll need to decide if you want to run a gauge with your setup.

Nicholas ★★★★★

Finally, a kit that actually accounts for the -8AN return line without needing adapters stacked on top of each other. The machining on the rail itself feels solid, and it bolted right up to my K24 without any clearance issues. Makes the engine bay look way cleaner than my old hack-job setup.

George ★★★★★

I was worried about fitment on my high-horsepower K-swap, but the kit's pre-fabricated lines aligned perfectly with my -8AN return setup. The anodized finish looks great under the hood and seems durable.

Grace Y. ★★★★★

Had my K-swapped setup running lean at high rpm before this kit, but the -8AN return line is a perfect match for the supply and solved the pressure drop immediately. Machining on the rail itself is clean and the fittings threaded on without any binding.
