Airtex 361 Mechanical Fuel Pump

Mechanical Fuel Pump Overview

Airtex 361 is a specific-fit mechanical fuel pump for classic Ford and Mercury applications. It is built for non-fuel-injected vehicles and is engineered to meet or exceed OEM specifications for fit and performance.

Compatible with Ford Mustang, Ford F-100, and Mercury Cougar applications listed below, this pump uses a hose-connection inlet and a threaded outlet for a direct mechanical fuel system replacement.

Key Features

• Mechanical fuel pump for external mounting
• Precision castings and hardened rockers for durability
• Advanced polymer diaphragm for consistent operation with multiple fuel blends
• 100% factory tested throughout manufacturing
• Gasket included; mounting hardware not included

Detailed Description

Airtex part number 361 is a mechanical fuel pump designed for classic Ford and Mercury vehicles that use a stock-style mechanical fuel delivery setup. The pump is intended for applications such as Ford Mustang, Ford F-100, Ford LTD, and Mercury Cougar, with fitment coverage spanning 1965-1976 depending on model and configuration. The design includes a 3/8-inch inlet thread size, a 1/2-20 UNF outlet thread size, and a 25 flow rating with 2.0 minimum pressure. Airtex 361 is factory tested for consistent output and is suited to replacement work on older carbureted fuel systems. This part cross-references Carter M6984 and Delphi MF0022 for the same application.

The Airtex fuel pump line focuses on OE-style mechanical replacement parts for classic and performance vehicles. For buyers restoring or maintaining older Ford and Mercury models, Airtex 361 provides a direct-fit option backed by manufacturing controls aimed at consistent performance.

What It Helps Address

• Hard starting caused by weak fuel delivery
• Fuel starvation under normal driving conditions
• Inconsistent pressure in carbureted fuel systems
• Wear-related loss of pump output
• Replacement needs on stock mechanical fuel setups

Installation Notes and Tips

Verify the vehicle uses an external mechanical pump and matches the listed fitment notes before ordering. A new fuel filter is recommended when replacing the pump. Confirm inlet and outlet thread sizes, and inspect the fuel lines and gasket sealing surfaces during installation.

Quality Assurance

Airtex states that this pump is 100% tested during the manufacturing process and built to meet or exceed OEM specifications for fit and performance.
