Universal Alloy Fuel Surge Tank Fuel Pump AN8 Fitting 2.5L .66 Gallon

Eliminate fuel starvation on your high-horsepower build with a 2.5L polished aluminum surge tank designed specifically for the legendary Bosch 044 fuel pump.

Keep Your Engine Fed Under Boost and G-Forces

When you're pushing serious power—whether it's a turbocharged street build, a dedicated track car, or a drag setup—fuel starvation isn't just a performance killer, it's an engine killer. The moment your fuel pump runs dry during a hard launch, aggressive cornering, or sustained high-G acceleration, you risk catastrophic lean conditions that can destroy pistons and valves in seconds. A surge tank solves this problem by creating a dedicated fuel reservoir that keeps your high-pressure pump constantly submerged and fed, no matter how hard you're driving.

This 2.5-liter polished aluminum surge tank is engineered to work seamlessly with the Bosch 044 fuel pump—the gold standard for high-performance fuel delivery. The 044 is capable of supporting 600-700+ horsepower when properly installed, and this tank ensures it receives unrestricted fuel flow at all times. Your factory or aftermarket lift pump fills the surge tank from your main fuel tank, while the 044 draws from the reservoir and feeds your engine. The result? Consistent, reliable fuel delivery whether you're pulling 1.5Gs on a road course or launching at full boost on the street.

Key Features at a Glance

• 2.5L (0.66 Gallon) Capacity: Large reservoir ensures your Bosch 044 pump stays submerged and fed during hard acceleration, cornering, and braking
• Designed for Bosch 044: Optimized dimensions and port layout work perfectly with the industry-standard high-flow fuel pump
• Multiple AN Fittings: Two AN10 ports (bottom for fuel feed/return), one AN8 port (top for vent/return), and two AN8 ports (middle for pump feed and auxiliary connections)
• Polished Aluminum Construction: CNC-machined dome design provides strength, durability, and a clean appearance in your engine bay or trunk
• Flexible Mounting Options: Compact footprint (10.25" height, 5.30" diameter) allows installation in engine bay, trunk, or along chassis rails
• E85 and Methanol Compatible: Aluminum construction handles corrosive race fuels without degradation

Installation & Setup

This surge tank requires a dual-pump fuel system: your factory or aftermarket in-tank lift pump feeds the surge tank, while the Bosch 044 (sold separately) mounts inside or alongside the tank to feed your fuel rail. The multiple AN ports allow you to configure the system for your specific needs—whether running a returnless setup, dead-head regulator, or traditional return-style fuel system. Professional installation and proper fuel system design are strongly recommended for safety and optimal performance.
