12AN to 10AN Y-Block 10AN to 8AN Y-Block

The REDHORSE PERFORMANCE 12AN to 10AN Y-Block and 10AN to 8AN Y-Block adapters are essential fuel system components for custom engine builds and high-performance fuel line routing. These dual-stage Y-block fittings allow you to split or combine hydraulic and fuel lines efficiently, making them indispensable for turbo systems, nitrous applications, and complex fuel delivery setups where space is tight.

Constructed from premium materials engineered for high-pressure fuel and fluid transfer, these Y-blocks feature ports that accommodate 12AN fittings for the primary inlet and split into 10AN and 8AN branches for precise distribution. Their compact 3.8 x 1.55 x 5.25-inch footprint and lightweight 0.33-pound design minimize installation complexity in cramped engine bays without sacrificing strength or reliability.

These adapters benefit builders, mechanics, and enthusiasts tackling fuel system customization on LS-swapped trucks, modified muscle cars, and competition vehicles where standard routing won't suffice. REDHORSE PERFORMANCE's reputation for precision engineering ensures consistent fit and leak-free operation under demanding conditions, whether managing fuel pressure in supercharged applications or coordinating multiple auxiliary systems.
