Product Overview

It supplies low-pressure fuel to the injection system on a wide range of agricultural and industrial equipment. A weak pump can cause extended cranking, fuel starvation under load or repeated need to hand-prime after shutdown.

The same engine family appears in many equipment brands; pump number and port layout are the best identifiers.

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: The same engine family appears in many equipment brands; pump number and port layout are the best identifiers.

Technical Specifications

  • Component: Mechanical fuel lift / transfer pump
  • Pulley reference: 85 mm on matching replacement catalogs
  • Ports: M16x1.5 inlet / M14x1.5 outlet on matching pump configuration

Frequently Asked Questions

How do I confirm this is the correct part?
Confirm the Deutz pump/reference number, pulley and threaded port sizes before installation.

Is this an OEM part?
Unless the listing is explicitly identified as genuine/OEM in the product data, treat it as a replacement component. Use the verified reference numbers, equipment application and physical configuration above to match your original part.

What should I check before installation?
Air leaks on the suction side can mimic a weak lift pump.

Fitment note: Equipment manufacturers may use different components within the same model family based on engine, serial number or production date. Confirm the original part number and machine/engine details before ordering.
