Choosing a replacement fuel pump for concrete paving and roadwork equipment is not just about price. You need a part that matches your engine's exact model, because a small difference in the mounting or fuel-delivery spec can make the pump useless in the field. The Fuel Pump 4941173 For Cummins B3.3 Road Construction Machinery is a targeted replacement option that narrows that decision to a specific set of 3.3L engines.
Quick verdict
If your concrete paving machine or roadwork equipment runs on a Cummins B3.3 (including the QSB3.3) or a Komatsu SAA4D95LE-5 3.3L engine, this new fuel pump is a practical buy at USD 303.05. The package contains one fuel pump and the part carries a 90-day warranty, so you have a clear window to confirm the fit after installation.
Who it suits
This pump is for anyone who already knows the engine family in their machine and wants a replacement component rather than a rebuild. It is a good fit for equipment owners who prefer to order by part number-4941173-and who can check their engine tag against the listed applications before committing.
What stands out from the listed details
The strongest point is the compatibility set: the 4941173 is linked to the Cummins B3.3, with the QSB3.3 specifically named, and to the Komatsu SAA4D95LE-5 3.3L engine. That gives you a concrete reference list when comparing against your machine. The pump is described as new, which simplifies the choice if you want a first-use replacement part.
Meaningful trade-offs
The main trade-off is that this is a replacement part, so your fit is only as good as your engine match. Before you order, confirm that your engine model number appears in the stated applications: Cummins QSB3.3 or Komatsu SAA4D95LE-5 3.3L. The listed package also contains just the pump itself, so you should plan to have any additional gaskets, seals, or mounting pieces handled separately.

Priced at USD 303.05, the Fuel Pump 4941173 For Cummins B3.3 Road Construction Machinery is a direct match when your equipment uses one of the named 3.3L diesel engines.

The limitation is that the fit depends entirely on your engine matching the listed models, so check thoroughly before you finalize the purchase.

The decision comes down to fit. If the engine in your concrete paving or roadwork equipment falls within the listed Cummins and Komatsu 3.3L models, the Fuel Pump 4941173 is a direct replacement part that keeps the purchase simple: one pump, one part number, and a 90-day warranty.
