Description

EC P9-DG Pro Rebuild Kit for Standard Volume (Single Stack, Gas) Carburetors


Professional Diaphragm & Gasket Kit for Racing Tillotson-Style Carburetors

The EC P9-DG Pro Rebuild Kit is specifically engineered for standard volume (single stack, gas) Tillotson-style carburetors used in high-performance kart racing and small engine applications. Whether you're tuning a 2-cycle engine or rebuilding a racing carburetor, this kit delivers race-ready reliability, precision, and performance.


Developed for professional racers, our EC Pro Gasket Kits use OEM-equivalent or superior aftermarket components—prioritizing durability under racing conditions over cost-cutting found in generic kits.


Key Features & Performance Benefits:

  • Fast Action Main Diaphragm
    An exclusive aftermarket upgrade that improves metering response and throttle precision. Features a smoother metal finish and a "wagon wheel" design for consistent dowel height and reliable fulcrum arm contact.
  • .020" Fuel Pump Diaphragm Gasket
    Standard for most Tillotson gas carburetors, this gasket holds less fuel volume, making it ideal for classes that restrict fuel delivery. For high-volume .040" gasket builds, we recommend the P1-DG kit if allowed by rules.
  • Essential Components Often Skipped in Other Kits
    Unlike many OE or aftermarket kits, the P9-DG includes the brass fuel strainer screen and cork gasket, ensuring a complete and clean rebuild—no need to buy extras.
  • Exclusive Assembly Diagram Included
    Every EC Pro Kit includes a full parts breakdown diagram to identify components and guide correct reassembly—essential for DIY racers and builders.


Kit Contents:

  • Fast Action Main Diaphragm
  • .020" Fuel Pump Gasket
  • .006" Fuel Pump Diaphragm
  • Brass Fuel Strainer Screen
  • Fuel Strainer Cork Gasket


Compatibility:

The P9-DG Pro Kit fits all standard volume (single stack, gas) Tillotson-style fuel pump carburetors, including popular racing models such as:
