Radium - Fuel Hanger Surge Tank for Nissan 350Z / Infiniti G35 & G37

The Radium Engineering Fuel Hanger Surge Tank (FHST) for Nissan 350Z, 370Z, and Infiniti G35/G37/Q50/Q60 is an innovative, all-in-one in-tank surge tank. It combines an enclosed surge tank and multi-pump hanger directly inside the factory fuel tank, curing severe fuel starvation issues during drifting, road racing, and drag launches without needing an external surge tank in the trunk.

Key Performance Features:

• True In-Tank Surge Tank: Features an enclosed chamber kept constantly full by return fuel and OEM siphon scavenging, keeping pumps 100% submerged at all times.
• Supports Staged Multi-Pumps: Accommodates 1 or 2 high-flow pumps with independent electrical feeds.
• Dead-Head or Return Style: Can be used with the built-in regulator or converted to an external return system with optional block-off kit.
• Odor-Free Cabin: Because the surge tank resides inside the factory fuel tank, there are zero fuel odors inside the vehicle cabin.
• Precision Billet Construction: Type-II anodized 6061-T6 aluminum for full E85 / race fuel compatibility.
