DIY Kit

For customers looking for even greater flexibility with their custom builds, look no further than the PERRIN Fuel Rail Junction Block. Choose from fuel rails and junction blocks to create the fuel setup that is perfect for you and your needs.

High-flow

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.

-6 AN fitting compatibility

The PERRIN Fuel Rail Junction Block 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.

Built-in Phenolic Spacers

All PERRIN Junction Blocks come with built-in phenolic spacers. These spacers insulate the junction blocks 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.

Construction & Finish

PERRIN 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.

Optional Fuel Rails

The 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.
