When a Cummins B3.3 engine in your concrete paving roadwork equipment starts to lose power or run unevenly, the fuel injection pump is a common point to check. The challenge is choosing a replacement that matches the engine family without guesswork. This guide looks at the Fuel Injection Pump 4941173, priced at USD 786.59, and what it offers for a roadwork maintenance decision. The goal is to help you decide whether this is the pump for your shop.
Quick verdict
This 4941173 is a new fuel injection pump for Cummins B3.3 road construction machinery. The part number is consistent across the manufacturer part number, interchange number, and OE/OEM number, and it comes with a 90-day manufacturer warranty. If your equipment uses a Cummins B3.3, this is a solid candidate to evaluate. For a direct replacement, that consistency takes some of the guesswork out of the order.
Who it suits
It suits a maintenance team that knows the engine family and wants a specific 4941173 replacement part for a B3.3 machine. The brand is CMP, and the application is road construction equipment. If you are ordering for a B3.3-powered paver, roller, or similar machine, this pump keeps the search focused. It also fits a shop that prefers to work from an established part number rather than chasing down a generic alternative.
What stands out
The strongest point is the way the part is identified: the model line and OE/OEM part number both point to the same engine family. This is a matched replacement part for that application, not a generic fuel component. That name alignment is useful whether you are ordering from a parts catalog or double-checking an existing inventory number.
Meaningful trade-offs
The main trade-off is the narrow fit. It is named for the B3.3 road construction application, so confirm your engine family before committing. It is a diesel pump, and the country of origin is China. Because this is a matched component, give yourself time to inspect the surrounding fuel system during the swap. The narrower the fit, the more important it is to verify the engine before you install.
Bottom line
For a Cummins B3.3 in concrete paving roadwork equipment, the 4941173 from CMP is a practical replacement option. Confirm the engine family, and the decision narrows quickly. If the engine family checks out, this is a straightforward replacement part to evaluate.
