Universal HydraMat 15x8 Center Outlet 3/8npt

The Holley Universal HydraMat 15x8 Center Outlet 3/8NPT is a fuel pickup reservoir designed for universal engine builds where space efficiency and reliable fuel delivery are critical. This modular fuel cell component features a center-mounted 3/8-inch NPT female outlet, enabling flexible fuel line routing and integration into custom fuel system configurations across a wide range of engine platforms and vehicle applications.

The HydraMat design measures 15 inches by 8 inches, providing substantial internal surface area for stable fuel pickup while maintaining a compact footprint suitable for tight engine compartments. The 3/8-inch NPT female outlet threads directly into standard fuel system components without adapters, simplifying installation and reducing potential leak points. This reservoir architecture supports consistent fuel delivery under acceleration, braking, and cornering loads—critical for performance tuning, racing applications, and custom hot rod builds where fuel starvation can compromise engine reliability. The cross-flow internal geometry ensures adequate fuel circulation and pressure regulation across variable operating conditions.

Builders and restoration specialists rely on the HydraMat platform for custom fuel cell conversions, fuel cell tank retrofits, and aftermarket fuel system fabrication. The universal design accommodates both carbureted and fuel-injected engines, making it a practical solution for vintage restorations, modern engine swaps, and high-performance builds where OEM fuel tanks are unavailable or inadequate. Each unit ships individually and integrates with existing Holley fuel system components and third-party manifold systems.
