Radium Pumpless High Volume Fuel Surge Tank - 10AN Center Pick-Up | Universal (20-0081)

External pump builds still starve in corners; the pumpless FST feeds them without duplicating hardware.

The Radium Engineering Pumpless Single 10AN Center Pick-Up High Volume Fuel Surge Tank serves builds that already run external pumps: designed for users that already have a secondary external fuel pump, it provides a reservoir from which the external pump can draw, featuring anodized aluminum pick-up tube architecture rather than an integrated internal fuel pump, and this FST model does not include a bulkhead wiring adapter so it is not suited for a pump inside it. The high volume canister carries a single 10AN center pick-up, feeding big external pumps at the flow rates serious builds demand.

What You'll Feel

• The external pump fed from a full reservoir through every corner and launch
• High-volume capacity buffering the biggest external pump draw rates
• A single 10AN center pick-up flowing what four-digit builds ask
• E85 and methanol confidence from the anodized aluminum construction

Features

• Pumpless high volume FST with single 10AN center pick-up; for external pump systems
• Extruded and machined 6061 aluminum canister; removable O-ring sealed billet caps
• Anodized and laser engraved; stainless hardware; factory pressure tested before shipment
• No bulkhead wiring adapter; NOT for internal pumps
• Most effective mounted vertically, tippable up to 45 degrees; horizontal mounting not recommended as the pick-up may draw air pockets
• Lifetime warranty on all Radium components

The Details

The pumpless architecture splits the surge duty from the pumping duty, with the lift pump filling the canister, the reservoir buffering, and the external pump drawing from the center pick-up that stays submerged regardless of what the chassis does; the high volume sizing extends the buffer for the draw rates external brushless and mechanical pumps run. The mounting orientation rule is load-bearing, since the pick-up geometry assumes vertical-to-45-degree installation, and horizontal mounting invites the air pockets the whole tank exists to prevent. Plumb the feed, return, and pick-up per your system's sizes, and the external pump never sees an empty inlet again.
