BuMatrivv Mechanical Fuel Pump M2152 for Wisconsin 4‑Cyl Engines — OEM‑Fit Direct Replacement, Reliable Fuel Delivery

BuMatrivv M2152 is a direct-replacement mechanical fuel pump designed to restore reliable fuel delivery on Wisconsin 4-cylinder engines used in vintage tractors, combines, and agricultural equipment.

If you operate or restore older farm machinery that originally used Wisconsin VE/VF/VG/VH series engines, the BuMatrivv M2152 offers a precision-fit mechanical pump to replace worn, leaking, or failing units. Manufactured to match OEM mounting and port locations, this pump works with a wide range of equipment from manufacturers such as John Deere, J.I. Case, Ford, Oliver, New Holland, Massey Harris and others that used Wisconsin 4-cylinder powerplants.

How will this pump fit my Wisconsin 4-cylinder engine?

The M2152 is engineered to align with the common bolt pattern and inlet/outlet positions found on many Wisconsin VE, VF, VG and VH family engines. It’s intended as a like-for-like replacement so you can swap it without modifying the engine. Confirming engine model numbers or the old pump part reference will help ensure compatibility.

• Direct compatibility with Wisconsin VE-4, VE-4D, VF-4, VF-4D, VG-4, VG-4D and VH-4 variants.
• Suits tractors and combines by John Deere, J.I. Case, Ford, Oliver, New Holland and Massey Harris that used these engines.
• OEM-style mounting flange and port locations for bolt-on installation.
• Designed to match pump lever stroke and diaphragm dimensions for correct fuel delivery.

What vehicles and years commonly use the M2152 pump?

This pump is suited to machines across a broad date range where Wisconsin four-cylinder engines were installed. Examples include post-1960 John Deere models, mid-1960s J.I. Case combines and early-1950s Oliver equipment. Use the engine code or original pump number to cross-check precise fitment.

• John Deere models from around 1969 onward equipped with VF-4 family engines.
• J.I. Case equipment from 1964–1970 using V4-type Wisconsin powerplants.
• Massey Harris clippers and New Holland machines using Wisconsin 4-cylinder engines.
• Classic Oliver and Ford units with Wisconsin VF/VE series engines.

What should I expect during installation and service life?

Installation typically requires removing the old pump, transferring any external fittings, and bolting the new unit into place using stock hardware. Because it follows OEM dimensions, the M2152 minimizes adjustments. Routine checks for leaks and secure mounting will keep the pump performing; longevity depends on fuel quality, engine maintenance, and environmental conditions.

• Bolt-on replacement—no modification for most original applications.
• Inspect gaskets and clamps; replace seals if they show wear.
• Keep fuel clean and free of debris to extend diaphragm life.
• Test fuel flow and engine idle after installation to verify operation.

Who is this for: The BuMatrivv M2152 is aimed at owners, restorers and mechanics working on vintage agricultural machinery powered by Wisconsin four-cylinder engines. If you maintain classic John Deere, Case, New Holland, Oliver, Massey Harris or Ford units and need a dependable mechanical fuel pump that matches original fit and operation, this part is built to replace worn OEM pumps and restore consistent fuel delivery.
