Universal HydraMat 15x8 Offset Outlet 3/8npt

The Holley Universal HydraMat 15x8 Offset Outlet 3/8NPT is a precision fuel pickup reservoir system engineered for high-performance and racing applications where fuel delivery reliability is critical. This modular fuel management component integrates seamlessly into custom fuel tank systems, providing controlled fuel draw from a submerged pickup tube that maintains consistent fuel pressure under demanding acceleration, deceleration, and cornering loads.

The 15-inch by 8-inch cross-baffled design prevents fuel slosh and cavitation during high-G maneuvers, a critical concern in motorsports where fuel starvation can cause lean-out conditions and power loss. The 3/8-inch NPT female outlet threads connect directly to fuel lines or fuel pump feed systems, while the offset outlet configuration accommodates tight tank geometries and unconventional mounting positions. Constructed for universal application, this HydraMat functions across carbureted, naturally aspirated, and forced-induction setups where traditional pickup tubes fail to deliver stable, aerated-free fuel supply. The modular design allows fabricators to position the unit anywhere within the tank volume, optimizing fuel capacity while maintaining surge-free delivery characteristics.

Typical users include street rod builders, circle-track competitors, bracket racers, and performance enthusiasts restoring or modifying vehicles with custom fuel system requirements. The HydraMat solves the common problem of fuel starvation during hard acceleration or sustained high-load conditions where fuel weight migration away from the pickup point causes momentary lean conditions. This component is particularly valuable in vehicles with modified tank geometry, aftermarket tank installations, or fuel systems requiring multiple pickup points to feed redundant pumps or carburetors.

Holley's HydraMat line represents the industry standard for modular fuel management in racing and custom automotive applications, offering proven surge suppression and consistent fuel delivery that direct-tube systems cannot match. The offset outlet variant accommodates the geometric constraints encountered in retrofit installations where standard straight connections interfere with tank baffles or structural reinforcements.
