AEM Multi Pump Fuel Surge Tank Fits Walbro AEM DW440

Radium Multi-Pump Fuel Surge Tank serves as a dedicated fuel surge reservoir and mounting solution that accepts popular 39mm diameter EFI pumps and provides integrated adjustable fuel pressure control for reliable fuel pressure management.

Designed by Radium Engineering, this multi-pump surge tank supports demanding EFI setups by consolidating pump mounting, pressure regulation, and a small-capacity reservoir into a single, serviceable unit. It is intended for end-user installation of compatible inline-style pumps (pumps not included).

• Compatibility with 39mm inline EFI pumps — Fits popular 39mm diameter fuel pumps with inline inlet/outlets, allowing use of widely available pump models without special adapters.
• Holds up to three pumps — Allows parallel pump configurations for increased flow capacity or redundancy, enabling higher fueling capability when multiple pumps are required.
• Integrated adjustable EFI fuel pressure regulator — Built-in regulator centralizes pressure control at the tank, simplifying plumbing and allowing on-tank adjustment of system pressure.
• Approximately 2 liter fluid capacity — Provides a compact reservoir volume to reduce fuel slosh and help maintain pump inlet supply in high-G or low-fuel conditions.
• Pumps sold separately — Allows the installer to select the exact pump model and flow rate appropriate for the application; tank accepts compatible inline-style pumps (not included).
• Adapter fittings inc — Includes adapter fittings to assist with plumbing into common fuel line configurations.
