Product Details：
Product Model: 0440020114
Product Type: Fuel Gear Pump
Fits Equipment: Diesel engines in trucks and machinery.
Core Function: Moves fuel from tank to engine's fuel injection system (stable pressure) for steady engine fuel supply.
Material Characteristics: Gears/pump body – high-strength alloy steel (wear/ corrosion-resistant); seals – oil-resistant rubber (no fuel leakage).
Installation Method: Fits original engine mounts and fuel ports; direct replacement, no extra mods.
The 0440020114 is a fuel gear pump for diesel engines in trucks and machinery. It pulls fuel from the tank and sends it to the engine's injection system with steady pressure – so the engine gets enough fuel when starting, accelerating or under heavy load, no power loss from low fuel.
Made of high-strength alloy steel, its gears and body resist wear from long-term fuel flow and corrosion from fuel impurities. Oil-resistant rubber seals stop fuel leakage, even when the engine is hot or vibrating. It fits original mounts and fuel pipes perfectly: take out the old pump, line this one up and fix it – no extra tweaks. Every unit is pressure-tested and leak-checked before shipping, reliable for long use.
Features And Advantages：
Stable Pressure, Enough Power: Makes steady high-pressure air, meets needs like braking and pneumatic tools for smooth work.
Durable & Adaptable: Key parts resist wear and vibration, handle temperature changes and dust. Passed tests, long life.
Easy to Install, Good Fit: Matches original mounts, direct replacement – no extra work, saves time.
Multi-Model Compatible: 13026014, SP106358, 13023181 are interchangeable, fit more equipment, easy to buy/replace.
Features and Advantages：
Stable Fuel Supply: Gear transmission gives even pressure (no sudden drops) and steady flow, meets engine fuel needs in different work conditions.
Durable & No Leakage: Alloy steel parts resist wear/corrosion; oil-resistant seals stop leakage – works well in harsh environments.
Easy Installation: Fits original mounts/ports; direct replacement saves repair time, no pro machining needed.
Good Adaptability: Works for diesel engines in trucks and machinery, fits common diesel types.
Application Scope ：
The 0440020114 fuel gear pump is mainly applied to Weichai diesel engines such as WP10, WP12, and WD615 series, as well as other engines equipped with the Bosch CP2.2 common rail fuel system.
It is widely used in heavy-duty trucks (HOWO, Shacman, FAW) powered by Weichai engines, and also in construction machinery (loaders, excavators, bulldozers) and diesel generator sets fitted with Weichai common rail engines.
Its function is to ensure a stable low-pressure fuel supply for the injection system, securing reliable engine performance during cold start, acceleration, and heavy-load operation.
FAQs ：
Q1: Can it be used for gasoline engines?
A1: No, only for diesel engines. Gasoline engines need different pressure – this may break the fuel system.
Q2: No fuel supply after installation?
A2: Check if pump is connected right to fuel pipes (no reverse); then check if fuel filter is clogged – clean or replace.
Q3: How to maintain?
A3: Replace fuel filter regularly to stop gear wear; check seals every 6 months – replace if leaking.
Q4: Need special tools to install?
A4: No, just common wrenches for bolts and pipes. Better have a technician do it (takes 30-60 mins) for correct connection.
