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.
PERRIN Junction Block bodies are precision CNC machined from 6061 billet aluminum with a black anodized finish for corrosion protection and a clean-looking finish. All ports are marked with "Feed" and "Return" for ease of installation.
