Product details

-6 AN Fuel Return Line Fitting is the perfect way to easily add a -6 AN fitting to any tank without welding or having access to the inside. By simply drilling a 1/2" hole, the fitting installs against the tank from the outside. By compressing the fitting aluminum body like a rivet, a mechanically secure, fuel tight seal is formed. Compatible with any tank material up to thick, installing the fitting does not require access to the inside of the fuel tank. While primarily intended for fuel return, the fitting has a number of other potential uses such as oil return, power steering line return, vent, etc. The fitting assembly includes a billet aluminum body, an anodized -6 AN fitting and a Grade 8 installation bolt for your convenience. This 6AN Fuel Return Line Fitting is designed to allow enthusiasts to add a fuel return line to their fuel system. This allows for a more efficient, cooler operating and higher horsepower capable system. Includes tool to install fitting. You can now add a return fuel line port to your fuel tank with only hand tools and no welding. The FAST and #174 EZ-Fuel EFI Return Line Fitting EZ-EFI and #174
