QFS-BKCN-01 is a heavy-duty universal bulkhead connector designed to safely pass high-amperage wiring through fuel pump assemblies or fuel cells without risking leaks or electrical shorts
High-Capacity Wiring: Engineered to accommodate two 10-gauge wires for high-draw pumps (like the Walbro 450/525), with additional space for a third smaller-gauge wire to support fuel level sending units
Ultimate E85 & Gasoline Protection: Features dual PTFE (Teflon) washers that create a chemical-resistant, airtight seal on both the top and bottom of the fitting, making it 100% compatible with pump gas, E85, and racing methanol
Eliminates Melted Connectors: The perfect solution for late-model Silverados, Mustangs, and F150s where the factory plastic bulkhead connector cannot handle the heat and amperage of high-performance dual-pump setups
GM Square Body Essential: A must-have for LS-swapping or upgrading GM Square Body hangers, allowing for a professional-grade electrical pass-through on metal or plastic sending unit lids
