Jetuplusllc 6AN Adapter Fitting Set for GM TBI & Vortec (Black) — M16/M14 to -6AN, Anodized

Compact black anodized aluminum adapter set that converts GM TBI and some Vortec metric O-ring fuel sending unit ports to -6AN fittings for feed and return lines.

When swapping engines or upgrading fuel plumbing, the right adapter prevents leaks and simplifies hose routing. This Jetuplusllc 6AN adapter fitting set (part number 47-0001BL) is made from anodized aluminum and designed to adapt common GM throttle body injection (TBI) and certain Vortec sending units to standard -6AN AN hose ends—ideal for LS swap projects and custom fuel systems.

Will this adapter fit my GM TBI or Vortec sending unit?

The adapter is intended for GM TBI-style sending units and many Vortec-style units that use metric O-ring ports. It converts the factory metric threads to -6AN for both feed and return connections, but always verify your sending unit thread sizes before purchasing.

• Feed port: M16 x 1.5 to -6AN
• Return port: M14 x 1.5 to -6AN
• Designed for metric O-ring style ports common on TBI and some Vortec units
• Confirm thread sizes on your sending unit to ensure compatibility

How does this fitting help during an LS swap or fuel system upgrade?

This adapter lets you connect modern AN braided hose and fittings to older GM sending units without modifying the unit or cutting new threads. That gives you cleaner routing, easier serviceability, and upgrades to higher-quality hose and fittings that are common in performance fuel systems.

• Enables use of -6AN braided hose for durable, high-flow feed/return lines
• Simplifies plumbing when swapping to LS engines or aftermarket fuel rails
• No permanent changes to the original sending unit required
• Black anodize resists corrosion and matches performance hardware aesthetics

What are the materials, finish, and sealing details?

The adapter is machined from aluminum and finished with a black anodized coating for corrosion resistance and a clean appearance. It uses metric O-ring style ports on the sending unit side and -6AN threads on the hose side; proper O-rings and thread engagement are necessary to prevent leaks.

• Material: machined aluminum for strength with low weight
• Finish: black anodized for abrasion and corrosion resistance
• Thread type: metric O-ring ports to -6AN hose fittings
• Manufacturer part number: 47-0001BL for easy ordering and reference

Who is this for? If you are an enthusiast or mechanic performing an LS swap, upgrading an older GM fuel system, or converting factory metric O-ring sending units to modern AN plumbing, this Jetuplusllc adapter set is built for your project. It’s aimed at people who want a straightforward, low-profile solution to mate factory sending units with -6AN braided hoses—especially useful when tidy hose routing, leak prevention, and durable fittings matter. Double-check your sending unit’s thread sizes (M16 x 1.5 for feed and M14 x 1.5 for return) before installing to ensure a correct fit and reliable sealing.
