Wadoy vacuum fuel pump kit for Cummins Onan P216G–P224G — 149-2187-01 replacement with filter & clamps

Wadoy 149-2187-01 is a direct-fit vacuum fuel pump kit designed to replace worn pumps on Cummins/Onan P216G through P224G engines and similar models.

This replacement assembly provides the pump, filter, clamps, and a cleaning brush to restore fuel flow in vacuum-style fuel systems. It is built to match the common dimensions and mounting points of legacy units used in many generators, welders and small engines. The kit is an economical aftermarket option that helps re-establish reliable fuel delivery when the original Onan or OEM pump shows signs of wear, clogging, or intermittent operation. Note: this is an aftermarket replacement and is not produced or endorsed by Cummins, Onan, or Jo-hn Deere; verify images and fit before purchase.

How will this pump restore engine starting and operation?

The Wadoy vacuum pump restores consistent vacuum-driven fuel flow so carburetors and fuel bowls receive steady supply during start and run. Replacing a leaking or clogged pump often resolves long crank times, stalling, or irregular idle. The included filter and clamps reduce the chance of introducing contaminants during installation.

• Replaces worn diaphragms that cause weak vacuum and fuel starvation.
• New filter captures debris that blocks fuel passages.
• Four clamps secure fuel lines to prevent leaks after installation.

Which engines and part numbers does this kit fit?

This pump is compatible with a range of Cummins/Onan engines and several Jo-hn Deere models commonly using vacuum fuel delivery. It is intended as a replacement for multiple legacy part numbers and fits applications like small generators, pressure washers, and lawn equipment.

• Supports Cummins Onan P216G, P218G, P220, P220G, and P224G engines.
• List-matched replacements: 149-1982, 149-1544, 149-2187, 149-2187-01.
• Also reports compatibility with Jo-hn Deere models F910, F930, 116, 316, 318, 420, 70, 90.

What’s included in the package and why each part matters?

The kit delivers a complete, ready-to-install set so you can replace the pump and related small parts in a single service visit. Providing the filter and clamps eliminates the need to source compatible accessories separately and helps ensure a clean, leak-free install.

• 1 vacuum fuel pump — the main replacement component for vacuum fuel delivery.
• 1 inline fuel filter — prevents dirt and varnish from entering the pump and carburetor.
• 4 stainless-style clamps — secure inlet and outlet hoses for a tight seal.
• 1 cleaning brush — helps remove buildup from hose ends and fittings prior to assembly.

How do I confirm fitment before buying?

Confirming fitment avoids returns: compare the pump’s mounting pattern, inlet/outlet locations and overall size against your old part. Check the listed replacement part numbers and your engine model stamped on the equipment data plate. If the images or dimensions don’t match your existing pump, don’t purchase.

• Match your current part number with the replacements listed above.
• Visually compare pump mounting holes and hose positions to photos.
• Measure overall length and inlet/outlet diameters when in doubt.

Who is this for: technicians, mobile mechanics, and owners of small generators, welders, skid steers and lawn tractors who need a cost-effective aftermarket replacement for vacuum-style fuel pumps. It’s suitable for anyone comfortable with basic engine maintenance and hose/clamp replacement who wants a complete kit to restore proper fuel flow without sourcing multiple parts separately. Remember: this product is an independent aftermarket replacement—confirm compatibility with your equipment before installing.
