This brass adapter is useful for connecting common 5/16" ID rubber fuel line to fuel pumps, pressure regulators, carburetors, or Tee fittings. Use with standard worm drive hose clamps. Sold individually.
Note: NPT nomenclature can be confusing because the nominal size refers to the inside diameter of the pipe, not the outside diameter of the threads. Male 1/8 NPT threads measure approximately 3/8" OD. For more information, check in our Guide to Using NPT Fittings.
