Product Description
CUMMINS Hose, tube, or pipe 4969171
1. Product Overview
CUMMINS Hose, tube, or pipe 4969171 is listed under source title “TUBE FUEL DRAIN QSK19”. It is classified for this pilot as hose, tube, or pipe within the engine fluid, air, or gas routing system. The source title references QSK19, but that association has not been independently verified for this pilot. Confirm the complete engine model, serial number, and arrangement before ordering.
2. Function and Operating Principle
A hose, tube, or pipe routes fluid, air, or gas between engine components. Diameter, length, bends, end fittings, pressure capability, temperature capability, and material must suit the exact circuit.
The line maintains a contained flow path while accommodating the installation geometry. Flexible lines may also isolate vibration and movement; rigid lines depend on correct alignment and support.
3. Application Status
| Manufacturer / brand | CUMMINS |
|---|---|
| Part number | 4969171 |

4. Typical Signs That Inspection May Be Required
| Observation | Possible significance |
|---|---|
| External leakage, staining, or wetness | May indicate cracking, loose connections, seal failure, or abrasion. |
| Kinks, collapse, or internal restriction | Can reduce flow and alter pressure or temperature. |
| Chafing or vibration damage | Shows inadequate clearance, support, or clamp condition. |
| Swelling, hardening, or heat damage | May indicate material deterioration or excessive exposure. |
These observations are inspection triggers rather than a confirmed diagnosis. Evaluate the complete engine system and follow the applicable manufacturer service information.
5. Inspection and Replacement Guidance
- Identify the media and circuit before selecting a line.
- Inspect fittings, clamps, supports, heat shields, and adjacent components.
- Do not force a rigid line into alignment or reuse damaged sealing interfaces.
- Confirm dimensions, fitting orientation, and arrangement-specific routing.
6. Information Required Before Ordering
- Complete engine or equipment model.
- Engine serial number and arrangement or configuration number.
- Installed part reference and clear photographs of the identification label.
- Installation position and related assembly information.
Compatibility notice: Verify 4969171 against serial-number-specific parts documentation before purchase or installation. Do not select the component by appearance or part-number similarity alone.
