175-2949 Advanced High Efficiency Fuel Water Separator for Caterpillar Diesel Engines
The 175-2949 fuel water separator protects Caterpillar diesel engines from water and contaminants. OEM cross-reference verified. Orders from IXIN Filter.
Description
This 175-2949 fuel water separator is an advanced-efficiency primary spin-on filter engineered as a direct replacement for the Caterpillar 175-2949, widely specified across CAT’s diesel engine lineup. It’s designed to strip water and fine contaminants out of diesel fuel before they can reach the secondary fuel filter and injectors, which are among the most expensive components to repair if contamination gets through.
Product Overview
The 175-2949 fuel water separator is built to remove essentially all free water and the majority of emulsified water suspended in diesel fuel, along with fine particulate contamination that a standard-efficiency filter might miss. As explained in this overview of fuel water separator function, water in diesel fuel can cause corrosion, microbial growth, and injector damage if it isn’t removed before reaching the engine.
As the primary filter in a two-stage fuel filtration setup, it takes on the bulk of the water-separation workload, reducing the strain on the secondary filter downstream and helping protect injectors from the erosion that contaminated fuel can cause.
Built as a spin-on filter with a standard 1-14 UNS-2B thread, it’s designed for straightforward installation during routine maintenance. Each unit is dimensionally verified against OEM measurements and tested for filtration performance before shipment — not just matched by part number.
Fits the Following Caterpillar Engines & Equipment
Fitment for this part number depends on your specific engine’s serial number range rather than a single fixed equipment list. Please confirm compatibility against your engine’s serial number and OEM cross-reference documentation before ordering, especially for bulk purchases.

Frequently Asked Questions
How much water does this filter remove from diesel fuel? It’s designed to remove essentially all free water and the majority of emulsified water, along with fine contaminants, before fuel reaches the secondary filter and injection system.
Is this a primary or secondary fuel filter? The 175-2949 is a primary-stage filter. It handles the initial, heavier water-separation load before fuel moves on to the secondary filter for finer filtration.
How do I know if this filter fits my Caterpillar engine? Fitment for this part depends on your engine’s specific serial number range rather than a fixed list of equipment models. We recommend confirming against your engine’s documentation or contacting us with your serial number before ordering, especially for bulk purchases.
Do you offer samples before a bulk order? Yes. We recommend requesting a sample for independent testing before committing to a bulk order, especially for first-time buyers.
