Description

Fuel Pump Top Plate for Tillotson 72mm & 76mm Racing Engine Blocks


The EC Fuel Pump Top Plate is engineered specifically for Tillotson 72mm (225-class) and 76mm (3" bore)performance blocks, which come from the factory without traditional front tank mounts. This clean, purpose-built design distinguishes Tillotson's racing engines from typical industrial blocks, delivering a sleeker, more performance-oriented appearance—and removing unnecessary mounting points that were never meant for racing.


Purpose-Built for Racing Applications

This top plate allows you to securely mount a fuel pump on Tillotson blocks that lack the factory fuel tank tabs. It’s the ideal solution for high-performance setups using:

  • Aftermarket slide carburetors
  • Diaphragm carburetors
  • Custom fuel delivery systems

If you're using a stock GX200/GX390-style float carburetor, we recommend pairing this top plate with our EC LK-156 Linkage Kit, which is designed for proper throttle operation on engines with original-style carbs.


Key Features:

  • Compatible with Tillotson 72mm & 76mm Blocks (225R/225RS and 3" big bore blocks)
  • Designed to mount pulse-driven fuel pumps cleanly and efficiently
  • Ideal for modified engines, mini bikes, karts, and open class builds
  • CNC-machined for precise fitment and long-term durability
  • Sleek top-mount design eliminates need for bulky tank brackets
  • Provides a clean, race-ready engine layout


Recommended With:

  • EC LK-156 Linkage Kit (for stock GX-style carbs)
  • Aftermarket PZ, VM, or HR-style slide carburetors
  • Pulse or vacuum fuel pumps (not included)


Compatibility:

  • Tillotson 225R / 225RS (72mm Bore)
  • Tillotson 76mm Racing Block (3" Bore)


Whether you're building a full race kart or a mini bike beast, the EC Fuel Pump Top Plate ensures you have a professional-grade mounting solution to complete your Tillotson performance build.

FAQ

Why do Tillotson 225R and 76mm blocks not have tank mounts?

Tillotson designed these racing blocks without front fuel tank mounts to distinguish them from industrial engines. This results in a cleaner, race-oriented design with fewer unneeded tabs or supports—ideal for performance builds.


What does this top plate do?

The EC Fuel Pump Top Plate allows you to mount a pulse-operated fuel pump directly onto your Tillotson 72mm or 76mm block. It’s critical for builds using slide or diaphragm carburetors that don’t have gravity-fed fuel systems.


Is this compatible with stock GX200 or GX390-style carburetors?

If you're running a stock-style float carburetor, we recommend using our LK-156 Linkage Kit alongside this top plate to retain proper throttle linkage function.


What carburetors is this top plate made for?

It's ideal for use with aftermarket slide carbs, like PZ22, VM22, or Tillotson HR-series, and any diaphragm carb setups that require a pulse-driven fuel pump.


Is a fuel pump included with this product?

No. This listing is for the top plate only. Pulse fuel pumps and linkage kits are available separately.
