Product Overview
It supplies low-pressure fuel to the diesel engine on multiple Thermo King unit families. A weak pump may cause extended cranking, shutdown under compressor load or repeated loss of prime after the unit sits.
Transport-refrigeration model suffix and engine package can change fuel-system parts.
Key Features & Performance
- Supports consistent fuel delivery: Provides the low-pressure fuel supply needed by the engine's injection or carburetion system.
- Useful for starvation symptoms: A weak pump can contribute to hard starting, loss of prime, hesitation or power loss once restrictions and air leaks are ruled out.
- Configuration-sensitive fitment: Mounting, ports, voltage/connector when applicable and reference number should be matched to the original.
- Product-specific note: Transport-refrigeration model suffix and engine package can change fuel-system parts.
Technical Specifications
- Voltage: 12V DC
- Component: Electric low-pressure fuel pump
