Fuel Tank Carb Conversion Fitting for Harley EFI to Carburetor
Best for vintage Harley enthusiasts seeking a billet stainless steel tank fitting to convert EFI back to carburetor without major system changes. The kit is designed for Harley-Davidson motorcycles from 1995 to 2001, matching the era’s fuel delivery arrangements. This option is particularly suitable for riders who want to preserve stock tank components while enabling carburetor compatibility. The primary advantage is a straightforward replacement that maintains compatibility with the original fuel lines. A potential limitation is the kit’s specificity to certain model years, so verify compatibility before purchase.
HOLDWELL 62052 EFI-To-Carb Conversion Kit
Best for 1995–2001 Harley-Davidson Touring models with Magneti Marelli systems. This kit is built to align with bikes that originally used electronic injection, offering a clean path back to carburetion. It’s particularly suitable for riders who want to maintain existing OEM components while enabling carburetor operation. A small caveat: ensure the Magneti Marelli configuration matches the kit’s fitment for your exact model year and trim.
Pingel Tank Adapter 62071
Best for builders seeking a machined, durable billet stainless steel adapter for EFI-to-carburetor transitions. The simplicity of the design makes it a good choice for custom setups or where a robust, repeatable connection is needed. One limitation is that this option may be best suited for certain tank and fuel-line configurations; confirm fit with your system before ordering.
OYOTE 62054 Delphi EFI-To-Carb Kit
Best for Harley-Davidson models that use Delphi components, offering a 100% brand-new design with high-quality materials. It is well-suited for riders who want a practical, durable conversion that aligns with Delphi-based assemblies. Caution: verify that the kit integrates cleanly with your bike’s specific Delphi arrangement to avoid compatibility issues.
Pingel Tank Fitting Kit 62054
Best for Delphi-based conversions requiring a dedicated tank fitting kit that matches the 22mm valve specification. This kit supports reliable fuel-line connections and is a logical upgrade for builders performing EFI-to-carb conversions. A potential limitation is compatibility with non-Delphi systems; confirm valve size and thread type before purchase.
Pingel Enterprise 62079 Tank Fittings Kit
Best for broader fuel-system integration projects, offering a larger fittings kit that can accommodate multiple configurations. This kit is suitable for shop environments or multi-bike applications where standardized parts simplify maintenance. Limitation: ensure the kit’s fittings align with your tank and line dimensions to avoid fitment issues.
Aeromotive EFI To Carburetor Fuel Pressure Regulator
Best for vehicles originally EFI-equipped that require precise carburetor output pressure control while retaining the EFI fuel system. The dual-stage design lets you bypass the EFI pump and regulate carb pressure independently, using stock EFI components where possible. Consider this option if your goal is to preserve OEM fuel system elements while achieving carburetor operation.
Buying Guide
What should you check before buying an EFI-to-carb conversion kit?
- Compatibility: Confirm model year, engine type, and whether the bike uses Magneti Marelli, Delphi, or other EFI architectures.
- Materials: Billet stainless steel and other durable metals resist corrosion and heat in motorcycle fuel systems.
- Fitting sizes: Ensure valve sizes and threads match your tank fittings and fuel lines (22mm, 1/4″ NPT, etc.).
- Installation scope: Some kits are plug-and-play; others may require intermediate components or professional tuning.
- Future maintenance: Choose kits with readily available replacement parts and clear installation instructions.
- Budget and availability: Consider lead times for parts and whether a kit’s scope matches your planned project.
