Line Separators; Size: 19.1mm ID Holes

The Line Separators from VIBRANT PERFORMANCE with 19.1mm ID holes are essential fuel and coolant line management components designed for custom automotive builders and performance enthusiasts who demand precision plumbing in their engine bays. These separators serve a critical function in high-performance and modified vehicles by organizing multiple hoses, preventing cross-contamination between separate fluid systems, and reducing vibration-induced chafing. Whether you're building a turbocharged street machine, a show car with custom cooling loops, or a competition engine, proper line management keeps your fuel delivery and cooling systems operating at peak efficiency while protecting against costly leaks or system failures.

These line separators feature a 19.1mm interior diameter hole pattern engineered to accommodate standard -10 AN hose fittings and similar fuel line specifications common in modern performance applications. The design allows multiple lines to pass through a single mounting point while maintaining controlled spacing and alignment, reducing the risk of hose failure from friction, heat transfer, or excessive vibration. VIBRANT PERFORMANCE manufactures these components to exacting tolerances, ensuring a secure fit that holds lines firmly in place without crushing or damaging delicate fuel or coolant hoses. The compact footprint (3.35 x 3.85 inches) makes these separators ideal for tight engine bay installations where space is limited, such as modern LS-powered builds, EFI conversions, or turbo engine swaps.

Mechanics and fabricators building custom fuel systems, upgraded cooling setups, or complex intake manifold configurations will find these line separators indispensable for professional-grade line organization. They're particularly valuable in race car builds, engine bay restorations, and any project where multiple fuel or coolant lines must be routed neatly and protected from damage. Installation is straightforward—simply bolt the separator to your engine block, frame, or custom firewall bracket using the mounting holes, then thread your hoses through the 19.1mm openings. Compatible with fuel injection systems, aftermarket fuel rails, auxiliary cooling systems, and any application requiring organized, vibration-resistant line management.
