Description

Stock 12-Hole Emulsion Tube for Honda GX390 & Big Block Clone Carburetors


Maintain peak fuel delivery and engine performance with this stock-style 12-hole emulsion tube, designed for Honda GX390 and GX390-style big block clone carburetors, including Predator 420 and Wildcat 460 models.


The emulsion tube plays a critical role in the carburetor by pre-mixing fuel and air before it reaches the venturi, where the mixture is atomized for efficient combustion. This ensures smoother throttle response, better fuel economy, and cleaner engine operation.


Whether you're tuning or rebuilding, this high-quality brass emulsion tube is a direct-fit replacement for most big block clone engines.


Emulsion Tube Specifications:

  • Overall Length: 1.182 inches
  • Number of Holes: 12
  • Through-Hole Diameter: ~0.100"
  • Material: Solid brass for corrosion resistance and durability
  • Fitment: Honda GX390-style carburetors and compatible clones (Predator 420, Wildcat 460)

Ideal for stock rebuilds, tuning, and replacing worn or clogged emulsion tubes.
