Radium Engineering FHST - Nissan 370Z (Walbro F90000267 / F90000274 / F90000285 Compatible)

When your Nissan 370Z is making serious power, the factory fuel system simply can't keep up. Cornering hard, pulling high-G loads, or running a built motor under boost — fuel starvation is a real threat. The Radium Engineering Fuel Hanger Surge Tank (FHST) eliminates that risk entirely, replacing your OEM fuel hanger with a precision-engineered surge tank assembly that keeps your injectors fed under every condition.

This listing is for the FHST housing and hanger assembly only — no pumps included. It is designed to accept Walbro F90000267, F90000274, and F90000285 series pumps, giving you full flexibility to spec the pump output that matches your power goals.

What Is a Fuel Hanger Surge Tank?

A surge tank is a small internal reservoir that sits inside your fuel tank, fed by a lift pump. The main high-pressure pump draws from this reservoir rather than directly from the tank floor. This means:

• No fuel starvation during hard cornering, braking, or acceleration
• Consistent fuel pressure at the rail regardless of tank level
• Reliable fuelling for high-horsepower builds that demand more than the OEM system can deliver
