Proflow Triple Fuel Pump Surge Tank – High-Performance Fuel Delivery Solution

Prevent Fuel Starvation Under Extreme Conditions

The Proflow Triple Fuel Pump Surge Tank is designed to prevent fuel starvation caused by fuel slosh or inadequate tank baffling during high-G acceleration, cornering, or hard launches. Whether you're hitting the track or the strip, this precision-engineered 3-piece billet surge tank system ensures consistent fuel delivery by maintaining a small fuel reserve for its internal fuel pump(s), supplying high fuel flow rates with only a minimal draw from the main fuel tank.

Effortless Fuel System Upgrade

Looking to boost your OEM fuel system without heavy modifications? This surge tank is the ideal upgrade for high-performance applications, including forced induction setups. Its innovative design integrates multiple pumps into a single -10AN ORB outlet, improving pressure equalisation and simplifying plumbing—no external couplers required. Thanks to built-in check valves in compatible fuel pumps, fuel pressure remains consistent at all times. Plus, with four integrated mounting points, installation is straightforward even in tight spaces.

Wide Fuel Pump Compatibility

Designed to accommodate all 39/40mm diameter fuel pumps, including top brands like:

Walbro (TI Automotive)
AEM
Deatschwerks
Proflow

Each pump is housed within NBR sleeves, reducing vibrations for quieter operation. The kit also includes two pairs of high-current stainless steel terminals with Teflon insulators, allowing you to stage fuel pumps for activation at different times.

Versatile Multi-Pump System

With support for one, two, or three pumps, this surge tank adapts to your fuel system’s needs. If you're using fewer than three pumps, the necessary port plugs are included. Also included is an in-tank wiring kit, featuring high-current 14-gauge wiring, heat shrink, and eyelet terminals for a reliable electrical connection.

Optimised Port Design

Large central pump outlet port: -10AN ORB thread
Supply, return, and overflow ports: -08AN ORB threads
Ports can be stepped down in size with the appropriate fittings (sold separately).

Premium Billet Construction

Crafted from high-quality billet aluminium, this surge tank is black anodised to Australian Standard AS1231 (AA25) for superior corrosion resistance. It is fully compatible with ethanol-based fuels like E85 and methanol—perfect for high-performance applications.
