RADIUM Engineering 20-1990-02 FCST-X Fuel Cell Surge Tank with 2 Surge Pumps and 1 Lift Pump

The RADIUM Engineering FCST-X (Fuel Cell Surge Tank-10 Years) is a high-performance drop-in fuel surge tank system designed to eliminate fuel starvation in competition vehicles equipped with fuel cells. This complete system comes pre-assembled with three Walbro GSS342 high-pressure fuel pumps: two 255 LPH surge tank pumps and one 255 LPH lift pump.

Key Features:

• Pre-assembled with 3x Walbro GSS342 pumps (2 surge tank, 1 lift pump)
• Increased surge tank volume: 2.6 liters (up from 2.2L in previous generation)
• Fast pump access with only 9 bolts for complete service
• Integrated lift handle for easy fuel pump servicing
• Merged single 10AN ORB female threaded outlet
• One-way fill valves (355 LPH each) keep surge tank full
• Check valves on all pumps prevent back-flow
• Hermetically sealed high-current stainless steel electrical studs
• Enhanced rollover protection with 8AN rollover vent valve
• Compatible with 6, 10, and 10.5 gallon fuel cells

What's Included:

• Anodized aluminum fill plate (6x10 pattern, 24-hole)
• Pre-installed Walbro GSS342 surge tank pumps with filters
• Walbro GSS342 lift pump (loose in packaging for custom height adjustment)
• Stainless steel lift pump mounts (shallow and deep options)
• Anodized aluminum service handle and pump brackets
• 8AN ORB to 6AN male return fitting
• 10AN ORB to 8AN male pump outlet fitting
• 2AN ORB fuel level switch plug
• FKM sealing gasket and rollover protection seal
• FKM one-way fill valves (3)
• Electrical wire ring terminals and aluminum acorn nuts

Each Walbro GSS342 pump flows 255 liters per hour at high pressure, supporting up to 500+ horsepower per pump. The gerotor design ensures reliable, quiet operation at pressures from 15-90 PSI. The lift pump height is adjustable to match your specific fuel cell depth, and brackets are easily cut to length if needed.

Designed for professional racing and competition vehicles, the FCST-X is the result of 10 years of continuous improvement (kaizen) on RADIUM's proven fuel cell surge tank platform. The system is compatible with gasoline and designed for EFI applications requiring consistent fuel delivery under extreme cornering and acceleration forces.
