Product Description

The OMIX 17709.06 is an OE-style mechanical fuel pump designed for 1974-1990 Jeep CJ and Wrangler YJ models equipped with the 3.8L (232 c.i.) or 4.2L (258 c.i.) AMC inline 6-cylinder engine. If you're experiencing hard starting, engine stalling, rough idling, or fuel starvation at the carburetor, a failing mechanical fuel pump is a common cause - and this direct-fit replacement restores proper fuel delivery without modification.

A key distinguishing feature of this pump is its rear-facing fuel inlet fitting, which matches the factory fuel line routing on these specific CJ and YJ applications. Using a pump with the wrong inlet orientation can result in improper installation or fuel line stress. Built by OMIX to match OE specification 3228191, this pump covers CJ5, CJ6, CJ7, CJ8 Scrambler, and Wrangler YJ models and is backed by a limited 5-year warranty for long-term reliability.
