The CVP Fuel Max Inlet Elbow has the largest inside fuel passage available for a stock CV or Keihin carburetor, capable of flowing up to 45% more fuel than OEM inlets. The inlet accepts standard 1/4" hose, or to maximize flow can be used with 5/16" fuel line. CVP's inlet incorporates a single CNC milled solid brass design that will not crack. For instructions on how to remove your old inlet elbow and installation check out the article on Harley fuel elbow replacement. Includes new set of fuel line clamps.
