Adding a return fuel line fitting to your fuel tank is simple with the no-welding-required FAST EZ-EFI return line fittings. With only hand tools, no welding, and simply drilling the necessary hole, the fitting installs against the tank from the outside. By compressing the fitting's aluminum body like a rivet, a mechanically secure, fuel-tight seal is formed. Compatible with any tank material up to a 1/4 in. thick, installing these FAST EZ-EFI fittings does not require access to the inside of the fuel tank. While primarily intended for fuel return, they have several other potential uses, such as oil return, power steering line return, vent, etc. FAST EZ-EFI return line fitting assemblies include a billet aluminum body, an anodized fitting, and a Grade 8 installation bolt for your convenience.
