Detailed Description

Airtex 6774 is a specific-fit mechanical fuel pump for Chrysler and Dodge applications that use a non-electric, external pump design. It is intended for carbureted fuel systems where consistent pressure and flow are required, and it cross-references Carter M6774 and Delphi MF0112 for the same application. The pump is factory tested during manufacturing to verify operation before it leaves the line.

This part number, 6774, is a practical replacement choice for owners servicing a 1976-1978 Chrysler New Yorker, 1976-1978 Chrysler Newport, 1976-1977 Chrysler Town & Country, 1977 Chrysler Town & Country except High Performance, or 1976 Dodge Monaco. Airtex 6774 is built for direct mechanical replacement on the listed vehicles.

What It Helps Address

• Hard starting caused by weak fuel delivery
