2Pcs 6AN AN6 Fuel Adapter Fitting to 3/8 GM Quick Connect w/Thread EFI Female LS

6AN Fuel Adapter Fitting to 3/8 GM Quick Connect with EFI Female Thread

This 2 piece 6AN AN6 fuel adapter fitting set connects a 6AN line to a 3/8 GM quick connect port, with an EFI female threaded end for LS style fuel systems.

Overview

This 6AN AN6 fuel adapter fitting set is made for plumbing 6AN hose ends into a 3/8 GM quick connect fuel port. Each fuel adapter fitting threads onto a 6AN male end and locks onto the factory style 3/8 quick connect, which makes it a practical piece for EFI swaps and fuel system changes. The EFI female thread accepts a standard 6AN male fitting, so installers can bridge hard lines and braided hose in one step.

• 3/8 GM quick connect clip on the opposite end for factory style fuel ports
• EFI female thread allows direct 6AN male connection
• Sold as a 2 piece set for both feed and return style setups
• Machined body for a stable, leak resistant seal under fuel pressure
• Compact length keeps routing tight in crowded engine bays

On-The-Job Use
