Radium Engineering Electrical Bulkhead Stud Kit (Pack of 6) - 17-0048

The Radium Engineering Electrical Bulkhead Stud Kit (Part # 17-0048) is a precision-engineered solution for builders who need to pass high-current electrical connections cleanly and safely through a wall, panel, or fuel surge tank enclosure. Sold as a pack of 6 complete stud assemblies, this kit is purpose-built for performance fuel system applications — including legacy Radium fuel pump hangers and surge tanks that are not equipped with the latest anti-rotation studs — and is equally at home in fully custom installations where a reliable, sealed electrical passthrough is required.

Key Features & Benefits

• Hermetically Sealed Design: Each bulkhead stud is hermetically sealed, making it suitable for use in fuel-wetted environments and protecting against moisture intrusion that could cause shorts or corrosion over time.
• 30-Amp Rated Per Stud: Each of the 6 studs in the kit is individually rated to 30 amps, providing ample current capacity for high-draw fuel pumps like the Walbro F90000262 (gasoline) and Walbro F90000267 (E85) — common choices in performance builds.
• CNC-Machined 304 Stainless Steel Conductors: The electrically conductive stud itself is custom CNC machined from 304 stainless steel, offering excellent corrosion resistance and long service life in demanding fuel system environments.
• Insulating Sleeve Prevents Galvanic Corrosion: A dedicated insulating sleeve is included with each stud to prevent panel conduction and galvanic corrosion — a critical detail when mixing metals in a motorsport or high-performance build.
• Compatible with 10–12 AWG Wire: Each ring terminal is sized to accept 10–12 AWG wire, which is appropriate for high-current fuel pump wiring in performance applications.
• Anodized Aluminum Acorn Nut + Heat Shrink: The exposed areas are insulated by an anodized aluminum acorn nut and included heat shrink, significantly reducing the risk of accidental shorts.
• Dual Top Locking Nuts: Two locking hex nuts per stud ensure a secure, vibration-resistant connection that won't back off under race or track conditions.
• Universal Fuel Compatibility: The kit is compatible with all fuel types including gasoline, diesel, ethanol, methanol, E85, and other alternative fuels — no need to source different hardware for flex-fuel or methanol injection builds.
• No Special Tools Required: Installation requires only a drilled hole to the specified diameter — no tapping, welding, or complex machining needed.

Fitment

This is a universal kit, not vehicle-specific. It is designed to work with:

• Legacy Radium Engineering fuel pump hangers and surge tanks that are not equipped with the latest anti-rotation studs — this kit enables those units to be properly wired with a sealed bulkhead connection.
• Custom fuel system installations where a hermetically sealed, high-current electrical passthrough is needed through any panel or wall meeting the dimensional requirements above.
• Radium FST (fuel surge tank) conversions to accommodate a single Walbro F90000262 (gasoline) or Walbro F90000267 (E85) fuel pump.

Because fitment is determined by your panel thickness and drilled hole diameter rather than a specific vehicle application, verify your surge tank or panel dimensions against the specs above before ordering. If you have questions about compatibility with your specific Radium hanger or surge tank, our fitment team is available to help.

Frequently Asked Questions

Q: What is this kit actually used for?
A: The Radium Engineering 17-0048 Electrical Bulkhead Stud Kit is used to create hermetically sealed, high-current electrical passthroughs through a panel or wall. It's most commonly used with Radium fuel pump hangers and surge tanks — particularly legacy units without built-in anti-rotation studs — and in custom fuel system fabrication where wiring needs to pass cleanly through an enclosure without risk of fuel leaks or electrical shorts.

Q: Is this kit compatible with E85 or methanol fuel systems?
A: Yes. Radium Engineering states that this kit is compatible with all fuel types, including gasoline, diesel, ethanol, methanol, and E85. The hermetic seal and stainless steel construction make it appropriate for corrosive alternative fuel environments.

Q: What size hole do I need to drill for installation?
A: Each stud requires a hole drilled to 0.220″–0.234″ in diameter (a 15/64″ drill bit is recommended). Your panel or wall must also be between 0.262″ and 0.322″ thick for proper seating and sealing. No tapping or welding is required.

Q: What wire gauge do the included ring terminals accept?
A: The ring terminals included in the kit accept 10–12 AWG wire, which is the appropriate range for high-current fuel pump wiring in performance applications. Each stud is rated to 30 amps individually.
