Product Overview
The fuel supply pump moves fuel from the tank toward the carburetor or injection system. Hard starting, fuel starvation under load, an empty downstream filter, or low supply pressure/flow can point to the pump after hoses, filter restrictions, and tank venting are ruled out.
Caterpillar catalogs 153-6876 as a fuel-system lift/priming pump with a manual priming lever. Published Cat dimensions identify a roughly 53 mm body diameter and 109 mm overall length, helping distinguish it from similar-looking feed pumps.
Key Features & Performance
- Fuel delivery: Restores the low-pressure supply needed by the matching engine fuel system.
- Repair-focused replacement: Useful when the original pump no longer develops adequate flow or has developed a leak.
- Fitment-specific connections: Port orientation, mounting, voltage where applicable, and reference number should be compared before ordering.
