Product Overview
A diesel heater that starts its fan and glow cycle but never receives fuel may have a failed dosing pump, a blocked line, air in the system, or no pulsed power from the controller. This pump meters small pulses of diesel from the tank to the heater rather than acting like a continuous automotive fuel pump.
Choose it only after confirming a 12-volt system and comparing the removed pump's body, electrical plug, hose connections, flow direction, and controller requirements. Heater brand, pump frequency, mounting angle, and fuel-line size matter more than vehicle make because this is used in many cars, trucks, vans, campers, and equipment installations.
Key Features & Performance
- Pulsed fuel-metering design for diesel air heaters
- 12-volt electrical operation
- Covers compatible heater outputs from 1kW through 5kW
- Directional inlet and outlet flow
- Compact inline format for auxiliary-heater fuel circuits
Common Uses
- Replacing a pump that no longer clicks during the start cycle
- Correcting confirmed low or interrupted fuel delivery to the heater
- Repairing a leaking or internally stuck dosing pump
- Completing a compatible replacement-heater installation
Technical Specifications

- Voltage: 12V DC
- Heater Range: Compatible 1kW-5kW systems
- Fuel: Diesel; verify heater requirements
- Operation: Controller-pulsed metering pump

Installation & Fitment
- Confirm the arrow on the pump points toward the heater
- Mount at the angle recommended by the heater manufacturer so air can clear the pump
- Use fuel-rated hose and secure every connection against air leaks
- Do not connect constant 12V power; the heater controller must pulse the pump
- Prime the line with the approved controller procedure and check for leaks before running unattended
Compatibility Notice
Northline Parts does its best to list all known compatible models, but the correct part may fit an application not shown.
Model, production date, serial number, engine or equipment configuration, installed options, and previous repairs can affect fitment. Compare the original part, identifying numbers, dimensions, connections, and mounting details before purchase.
Frequently Asked Questions
Q: Why does a heater pump click instead of run continuously? A: A dosing pump delivers measured pulses of fuel. The clicking normally follows commands from the heater controller.
Q: Will this work with gasoline? A: It is listed for compatible diesel parking-heater systems. Do not use a fuel the heater or pump manufacturer has not approved.
Q: Can a no-start heater always be fixed with a pump? A: No. Check voltage, controller pulse, glow plug, combustion air, exhaust, fuel filter, and air in the line before replacing parts.
Q: How do I know the pump is the right size? A: Compare voltage, heater output range, hose connections, mounting direction, and the specifications on the removed pump.
