2003 GMC C4500 Topkick Fuel Injectors

CARDONE Remanufactured Mass Air Flow Sensors (MAFS) precisely track O.E. output curves and maintain specific tolerances to ensure accurate scan tool readings for proper operation. 100 percent re-soldering of critical components ensures superior electrical connections, eliminates intermittent failures and lengthens product life. With CARDONE Mass Air Flow Sensors (MAFS), you can expect smooth vehicle performance.

GM Genuine Parts Mass Air Flow (MAF) Sensors are designed, engineered, and tested to rigorous standards, and are backed by General Motors. These sensors are key parts of the engine management system, and are GM-recommended replacements for your vehicle’s original components. The MAF sensor measures the amount of air entering the engine so that the engine control module can determine the amount of fuel to inject. This helps ensure the most efficient airfuel mixture for the best fuel economy and power. GM Genuine Parts are the true OE parts installed during the production of or validated by General Motors for GM vehicles. Some GM Genuine Parts may have formerly appeared as ACDelco GM Original Equipment (OE).

Every single Delphi mass air flow (MAF) sensor that we manufacture – whether with or without the housing – is built with calibrated all-new components and is never remanufactured. Our mass air flow sensors are designed and tested to meet or exceed OE requirements, and engineered for a perfect fit in more than 180 million vehicles on the road today in North America – including makes from Ford, Toyota, Nissan, Volkswagen, Hyundai, BMW, Honda, GM, Mazda, Subaru, Acura and more.

MAHLE® gaskets provide world class sealing products trusted by OEMs & Technicians around the globe.

Complete kit includes banjo bolt seals to reseal injector fuel return rail manifold on Duramax LB7 engines.

Carquest premium remanufactured injectors are completely torn down, ultrasonically cleaned, inspected and remanufactured using premium components. Each injector is tested on a sophisticated flow bench under multiple operating parameters. This Carquest four-pack kit includes four cylinder-specific high-pressure fuel lines that should be replaced any time the injector is replaced. Replacing all four injectors at the same time with the fuel lines ensures a complete repair and reduces the chance premature injector failure due to contamination from the fuel line. This injector four-pack offers savings over purchasing single injectors and components separately.

The components in this fuel injector O-ring kit are designed to match the fit of the original O-rings on specified vehicles. They are engineered to help ensure leak-free connections to the fuel injectors during service or when the rings are damaged.

This fuel pressure regulator is engineered to match the function of the original equipment regulator on specified vehicles. It is engineered to help ensure proper fuel injection pressure when the original regulator has failed or is malfunctioning.

WVE is a leading source of advanced vehicle electronics components for replacement applications in the automotive aftermarket and original equipment applications. WVE offers high-technology manufacturing along with innovative solutions and improvements to OE designs. Every component either matches or improves on the OE design to ensure fast, easy installation, superior performance and reliability.

This common rail diesel fuel injector has been thoroughly remanufactured using an exclusive process to ensure optimum quality and reliability. Critical components are replaced and clearances are verified after cleaning, reassembly and testing.

A common problem on the Duramax LLY engine is contamination of the fuel fittings resulting in injector failure when serviced. Corrosion can form between the line and injector nut and fall into the injector when the line is removed or installed. Replacing the line at time of injector replacement or service is highly recommended to reduce injector failure due to contamination. CARQUEST premium fuel lines meet or exceed critical OE performance specifications for sealing and burst pressure.

Complete injector seal kit includes all necessary components to properly reseal four injectors on one bank of the Duramax LB7 engine.

Modern vehicles may have 100 or more electrical harness connectors in every operating system of the vehicle. Terminal tension may weaken with time or corrosion may occur within the connector housing making replacement necessary. When replacing any harness-connector assembly approved wire termination methods must be followed to ensure a successful and long-term solution to the original problem is made. A failed terminal connection, terminal corrosion or damaged wire will result in an electrical system fault.
