Fuel System Parts: OEM Quality & Durability

Aging of heavy equipment fuel systems is a serious concern, as they can lead to significant degradation in engine performance. Especially in off-highway machinery such as skid steer loaders, backhoe loaders, and excavators, fuel systems often experience fuel filter blockage, carburetor failure, fuel line rupture, and fuel injector or fuel pump failure. Therefore, it is necessary to promptly check and update damaged parts in the fuel system. A well-functioning fuel system keeps your off-road machinery running efficiently by delivering fuel smoothly, boosting performance, and reducing emissions. FridayParts knows the importance of every component when working under harsh conditions, so we provide precision engine replacement parts, including fuel lift pumps, pump heads, and throttle bodies, to restore reliable fuel delivery and engine performance. Our catalog offers OEM-quality replacement parts for all major engine brands to keep your equipment in top shape. Whether in terms of price or quality assurance, FridayParts is a good choice that you can trust.

Fuel System Parts Catalog

Injectors & Nozzle

Injectors spray fuel into the combustion chamber for optimal combustion, with the nozzle controlling the spray pattern and fuel distribution. They are typically installed on the cylinder head.

Pump Head & Rotor

These components work together to pressurize and deliver fuel to the injectors, ensuring the correct amount of fuel is delivered at the right time.

Injection Pump

It's the heart of the fuel system, usually located at the engine block or cylinder head. It pressurizes and delivers fuel from the tank to the injectors, ensuring proper pressure and timing.

Throttle Body

It regulates air entering the engine to control speed and performance, working alongside fuel injectors to balance the fuel-to-air mixture.

Fuel Pump

Draws fuel from the tank to the engine, with external pumps typically featuring threaded connections and internal pumps connecting to a pre-filter for seamless fuel delivery.

Fuel Line

The fuel line carries fuel from the tank to the engine and other fuel system components, ensuring consistent flow throughout the system.

Injector Seal Kit

It ensures a tight seal between injectors and the cylinder head, preventing leaks and maintaining injector performance.

Common Rail Assembly

Supplies fuel to each injector at the correct pressure, ensuring precise and synchronized fuel delivery.

Injection Pump Repair Kit

Contains components to repair a malfunctioning injection pump, restoring it to optimal condition and avoiding costly replacements.

Carburetor

Mixes air and fuel for older engine systems, ensuring efficient combustion before fuel injection systems became common. It is a vital part of engine spare parts for these older models, contributing to the overall efficiency and performance of the engine.

FAQs

What Are the Common Signs of Fuel System Failure?

Loss of power, poor acceleration, misfires, and increased fuel consumption often signal a failing injector, clogged fuel filter, or weak fuel pump.

How Do I Choose the Correct Fuel Injector or Pump for My Machine?

Refer to your equipment’s OEM part number, or contact our support team to cross-reference and ensure a precise fit.

Are Electric Fuel Pumps Better than Mechanical Ones?

Electric fuel pumps provide more consistent pressure and are often easier to install in modern systems, especially where space is limited.

Do Your Parts Support Older and Newer Machine Models?

Yes. We carry fuel system parts compatible with a wide range of makes and models, both legacy and current.
