Review GMB Jeep Mechanical Fuel Pump fits CHEROKEE 1974–1983

The GMB 520-8020 mechanical fuel pump is a high-performance replacement component designed specifically for Jeep Cherokee models manufactured between 1974 and 1983. This fuel pump is an excellent upgrade for vehicles experiencing fuel delivery issues, helping to ensure reliable and consistent engine performance.

Measuring approximately 2.8 inches long, 1.6 inches wide, and 1.2 inches high, this mechanical fuel pump is compact yet robust. The pump housing is engineered from durable cast aluminum, which not only enhances its structural integrity but also provides excellent heat dissipation properties. This feature is particularly beneficial in older vehicles, which can generate significant heat during prolonged operation.

The GMB 520-8020 fuel pump comes with a high-output, 7-blade impeller, which is designed to deliver fuel efficiently to the carburetor or fuel injection system. The impeller's advanced design ensures smooth fuel flow, even under heavy load conditions.

The fuel pump also features an integrated bypass valve, which helps prevent fuel starvation during engine cranking. This valve automatically opens during starting, allowing fuel to reach the engine while the pump is priming. Once the engine is running, the bypass valve closes, ensuring that fuel is delivered directly to the carburetor or fuel injection system for optimal performance.

The GMB 520-8020 mechanical fuel pump is designed to be a direct replacement for the original equipment on 1974 to 1983 Jeep Cherokee models. It uses the same mounting points and electrical connections as the factory unit, making for a straightforward and hassle-free installation process.

This fuel pump is also compatible with various fuel filter configurations, allowing users to install their preferred filter setup. The pump's inlet and outlet threads are standard AN-6, which is commonly used in automotive fuel systems.

With its robust design, high-performance impeller, and easy installation, the GMB 520-8020 mechanical fuel pump is an excellent choice for Jeep Cherokee enthusiasts looking to improve their vehicle's fuel delivery system and ensure consistent engine performance.
