    Subaru Junction Block with FPR and -6 Fittings by Perrin Performance

    DIY KIT For customers looking for 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 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), untilizing 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 200F cylinder heads, this keeps fuel closer to its normal ambient temperature. These spacer reduce the temperature of the fuel upwards of 30°F
