Manufactured in Clackamas, Oregon, USA, this kit uses a 12-bolt attachment design that clamps directly onto the existing fill plate, distributing load evenly across the cell without requiring additional drilling or custom fabrication. Whether you are building a new motorsport fuel system or upgrading an existing Radium FCST assembly, this kit provides a clean, reliable, and repeatable mounting solution.\u003c\/p\u003e\n\u003ch4\u003eWhy the 12-Bolt Design Outperforms Older Mounting Methods\u003c\/h4\u003e\n\u003cp\u003eTraditional fuel cell mounting strategies often rely on 4 or 6 discrete attachment points, concentrating stress at a small number of locations on the fill plate perimeter. Under race conditions, vibration, hard cornering, and fuel load shifts can fatigue the fill plate at those stress concentrations over time. The Radium Engineering mounting tab kit addresses this by spreading clamping force across 12 of the 24 fill plate bolts, roughly doubling the number of load-bearing points compared to a 6-bolt approach and tripling those of a 4-bolt bracket. This larger contact footprint reduces peak stress at any single bolt location, improves vibration resistance, and keeps the fuel cell seated firmly without distorting the fill plate flange. The result is a more durable, longer-lasting installation that requires less periodic re-torquing.\u003c\/p\u003e\n\u003ch4\u003eMaterial and Construction\u003c\/h4\u003e\n\u003cp\u003eThe mounting tabs are laser cut from \u003cstrong\u003e5052 aluminum sheet\u003c\/strong\u003e, a marine-grade alloy chosen for its excellent corrosion resistance, good formability, and high fatigue strength relative to its weight. After cutting, each tab is thoroughly deburred to remove any sharp edges left by the laser process, then finished with a \u003cstrong\u003eblack anodize\u003c\/strong\u003e coating. Anodizing integrates into the aluminum surface rather than sitting on top of it, producing a finish that resists chipping, peeling, and chemical attack from fuel vapors, brake fluid splash, and chassis cleaning solvents. The two-piece tab design allows the assembly to bridge the fill plate without requiring a single large stamping, keeping part weight low and material utilization high.\u003c\/p\u003e\n\u003cp\u003eSealing integrity at every bolt location is handled by the included \u003cstrong\u003e36 black nylon sealing washers\u003c\/strong\u003e. Nylon washers prevent direct metal-to-metal contact between aluminum hardware and the fill plate, reducing galvanic interaction and providing a compliant seating surface that maintains consistent clamp load as temperatures cycle. Twenty-four washers are sized for the fill plate bolts and 12 are designated for the mounting tab bolts themselves.\u003c\/p\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eThis kit is compatible with any fuel cell that uses a \u003cstrong\u003estandard 6-inch by 10-inch 24-bolt fill plate\u003c\/strong\u003e, including cells from the following manufacturers:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eFuelSafe\u003c\/li\u003e\n\u003cli\u003eATL\u003c\/li\u003e\n\u003cli\u003eJaz Products\u003c\/li\u003e\n\u003cli\u003eHarmon\u003c\/li\u003e\n\u003cli\u003ePyrotect\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eRadium FCST compatibility is limited to legacy models only.\u003c\/strong\u003e This kit is designed for and compatible with Radium Engineering FCST assemblies in the \u003cstrong\u003e20-014X-XX and 20-049X-XX series\u003c\/strong\u003e.
