High-quality fuel pump with large connector 4D0971992N for EA211 1.4T/1.2

Detailed Product Overview

This high-quality fuel pump equipped with a large connector is produced in strict accordance with original factory specifications, matching the OE number 4D0971992N and perfectly adapting to EA211 1.4T and 1.2T engine models. As the core component of the vehicle fuel supply system, it undertakes the task of stably pumping fuel from the fuel tank to the engine combustion chamber. It maintains a constant fuel delivery pressure under various driving conditions such as cold start, urban stop-and-go traffic, high-speed cruising and heavy load acceleration, ensures accurate fuel injection volume of the engine, realizes complete fuel combustion, effectively improves power output performance and fuel economy, and avoids abnormal shaking, insufficient acceleration and flameout caused by unstable oil supply.

The wiring interface of this fuel pump adopts a special large-size connector design consistent with the original part, with completely matched pin positions, wiring layout and locking structure. It can realize plug-and-play direct connection with the original vehicle wiring harness without wiring modification, wiring cutting or connector conversion, which greatly reduces the difficulty of installation and the hidden danger of circuit failure caused by improper modification. All the overall dimensions, fixed buckle positions and installation radian of the pump body are 1:1 copied according to the original design, which can be perfectly embedded in the fuel tank installation position of the vehicle.

Core Product Advantages

1. Rugged structure with high wear resistance and corrosion resistance
The internal fuel pumping rotor is made of wear-resistant alloy material, which can resist the long-term scouring and chemical corrosion of gasoline containing impurities and additives. The built-in high-precision pressure regulating valve can automatically adjust the fuel supply pressure within the standard range all the time, prevent excessive or insufficient oil pressure, and effectively extend the service life of the fuel injector. The sealed shell structure can isolate the gasoline vapor inside the fuel tank, reduce the risk of internal parts oxidation and failure.

2. Customized large connector for reliable circuit connection
The exclusive large-size integrated connector has tight clamping force, good vibration resistance and high temperature resistance. It will not cause virtual connection, power failure or poor signal contact under the bumpy road conditions and high temperature environment inside the fuel tank for a long time, effectively solving the common faults such as intermittent fuel supply interruption and sudden power loss caused by loose wiring terminals of ordinary fuel pumps.

3. Multi-layer strict factory quality inspection system
Each finished fuel pump will pass continuous fuel supply pressure test, long-time operation durability test, high and low temperature aging test and connector conductivity detection before leaving the factory. All assembly errors are controlled within the original equipment tolerance standard, which effectively avoids early failures such as pump stalling, oil pressure drop and connector burnout in daily driving.

4. Wide application scenarios and outstanding cost performance
It is specially developed for vehicle maintenance, fault emergency repair and fuel system overhaul of EA211 1.4T and 1.2T engines. It is a cost-effective replacement choice compared with expensive official original fuel pumps for auto repair workshops, vehicle modification enthusiasts and private car owners.
