MOTOALL Carburetor Kit for Onan P216G P218G P220G — 146-0496 Replacement with Vacuum Fuel Pump & Filter

The MOTOALL 146-0496 carburetor kit is a complete replacement assembly — carburetor, vacuum fuel pump, fuel filter, gaskets and hoses — engineered to restore fuel delivery on compatible Onan small engines.

If your Onan-powered generator or engine shows rough idling, hard starting, or fuel leakage, this MOTOALL kit provides the main components needed for a reliable rebuild. Designed to work with a range of Miller/Onan models including P220G, P216G and several OL/LX series units, it matches the original part numbers and mounting dimensions so installation fits standard layouts. The set includes the carburetor itself plus a vacuum fuel pump, fuel lines, clamps and a filter — everything to replace worn fuel-system parts and return consistent fuel-air mixing.

How does the carburetor kit improve engine performance?

By restoring proper fuel metering and vacuum feed, the kit helps the engine run more smoothly under varied loads. Replacing aged seals, filters and the vacuum pump reduces fuel leaks and inconsistent idling without changing engine tuning.

• Improved fuel-air mixture for steadier idling and smoother throttle response.
• New fuel filter and hoses prevent debris-caused blockages.
• Vacuum fuel pump restores reliable fuel delivery when equipped on the engine.

What are the key dimensions and mounting details I need to know?

Match the physical dimensions and hole centers before purchase to ensure fitment on your carburetor flange and intake manifold. The kit adheres to the common Onan sizing used on the listed models.

• Larger bore outer opening: 2-1/32" outside diameter (OD).
• Smaller bore inner opening: 1-1/16" inside diameter (ID).
• Carburetor mounting hole centers measure 2-3/8" across.

What’s included in the package and what should I expect during installation?

The kit ships with everything required to replace fuel delivery components; basic mechanical skills and common hand tools are adequate for installation. Use included gaskets and clamps to avoid air or fuel leaks during reassembly.

• 1 complete carburetor (146-0496 style) with mounting gasket.
• 1 vacuum fuel pump, 1 inline fuel filter, fuel lines and 4 hose clamps.
• Simple steps: remove old carburetor and pump, transfer any necessary linkage, install new gasket, secure hoses and clamps, test for leaks and proper idle.

Who this is for: technicians, DIY mechanics and fleet managers who maintain Miller/Onan generators and small engines will find this MOTOALL kit a cost-effective way to replace worn fuel-system components. It’s well suited for restoring older generators that need reliable fuel metering without sourcing multiple separate parts. If you need an OEM-compatible carburetor, matching pump and all necessary installation hardware in one shipment, this kit is targeted to that need. Note: verify model compatibility and dimensions before ordering; professional installation is recommended for unfamiliar users.
