For customers looking for even greater flexibility with their custom builds, look no further than the PERRIN Top Feed Fuel Rail DIY Kit. Some custom fuel setups only require fuel rails and not a junction block, and this kit is here to fill that requirement.
PERRIN Top Feed Fuel Rails incorporate large 0.520" inside diameter channels for maximum fuel flow. This allows for cars to run beyond 800 WHP safely and without inconsistent fuel flow to each cylinder.
The PERRIN Fuel Rail DIY Kit is threaded for male 9/16-18 fittings, utilizing an O-ring seal. These are the same as a typical -6 AN fitting with an O-ring seal, also referred to as ORB fittings. These fittings are widely available and in all shapes and colors--whatever suits your build.
All PERRIN Fuel Rails come with built-in phenolic spacers. These spacers insulate the fuel rails from the 200°F cylinder heads. This keeps fuel closer to its normal ambient temperature. These spacers reduce the temperature of the fuel upwards of 30°F.
PERRIN Fuel Rail bodies and junction block bodies are precision CNC machined from 6061 billet aluminum with black anodized finish for corrosion protection and a clean looking finish. All ports are marked with "Feed" and "Return" for ease of installation.
The PERRIN Fuel Rail Junction Blocks make for a clean transition from OEM rubber hoses to your PERRIN Fuel Rails. Like the PERRIN Fuel Rails, the PERRIN Junction Blocks are threaded for male 9/16-18 fittings (-6 AN), utilizing an O-ring seal.
