Description

141-89 Tillotson HW Standard Volume Fuel Pump Body – Single Stack (Gas)


The 141-89 Tillotson Fuel Pump Body is a standard-volume, single-stack pump plate designed for gas-powered Tillotson HW carburetors. This is the top aluminum plate in the fuel pump stack assembly and is essential for proper fuel delivery in standard applications.


Known for their reliability and modular design, Tillotson carburetors have used virtually the same fuel stack configuration since their inception—proof of their consistent performance across generations of small engine applications.


Key Features:

  • OEM-style part number: 141-89
  • Standard volume configuration (single stack, for gasoline use)
  • Fits all Tillotson HW model carburetors and many compatible models
  • Durable aluminum construction for long-lasting performance
  • Designed for engines running gasoline, not alcohol/methanol
  • Easy to install; part of the modular Tillotson carburetor system


Modular Compatibility:

Tillotson carburetors are designed with a modular fuel system, allowing users to swap fuel pump bodies and stacks based on fuel type and performance needs. However, standard volume (single stack, gas) and high volume (double stack, alcohol) pump systems are not interchangeable.

For alcohol/methanol applications (such as racing), it's common to upgrade to the high-volume pump stack, but this requires both pump plates and bodies to match.


Application:

Perfect for standard gasoline applications, rebuilds, or restorations of Tillotson HW carburetors. Whether you're servicing small engines, karting engines, or performance setups running gas, this fuel pump body ensures reliable fuel delivery.
