Bulkhead 2 Wire Fitting Wire-Thru

The Bulkhead 2 Wire Fitting Wire-Thru by ATL Fuel Cells is a precision firewall grommet engineered for professional fuel cell and high-performance fuel system installations. This component is essential for mechanics and fabricators routing dual-wire fuel pump connectors, level senders, or other electrical leads through vehicle firewalls while maintaining complete electrical isolation and protection from engine heat and vibration. Whether you're building a custom race fuel system, upgrading to an ATL fuel cell in a street rod, or performing a full fuel system modernization, this wire-thru fitting prevents chafing, corrosion, and electrical shorts that can compromise safety and reliability.

Constructed from durable black plastic, the Bulkhead 2 Wire Fitting features a 0.375-inch inner diameter suited for standard 2-wire connector bundles, with a 1-inch outer diameter flange that sits flush against the firewall. The 1.45-inch wall thickness ensures a secure, sealed fit that protects wiring from direct contact with sharp firewall edges and maintains a clean, professional appearance. The two-wire design accommodates fuel pump power and ground lines simultaneously, reducing clutter and installation complexity compared to individual wire passes. This compact, lightweight component (0.03 lbs) integrates seamlessly into tight engine bay layouts without adding bulk or requiring extensive modification.

This wire-thru grommet is ideal for hot rod builders, professional fabricators, and DIY enthusiasts upgrading fuel systems in classic vehicles, race cars, and performance builds where ATL Fuel Cells components are specified. Installation is straightforward—drill or punch a hole in your firewall, press the grommet through, and route your connector bundle through the center. Compatible with all standard 2-wire fuel pump connectors and ATL Fuel Cells pump assemblies, this fitting ensures code-compliant, safe electrical routing on any vehicle platform.
