Q: Would it fit for my JEEP CJ5 1979 6cylinder?  Answer this question

A: Hello Cdlvs294, this Howell Fuel Injector Kit will not work with your 1979 Jeep CJ5. This kit fits Jeep CJ's from 1981 to 1986.

Howell Engine Developments, Inc. was formed in 1988 by two brothers who wanted to turn their passion for classic cars into their career. The company focuses on producing fuel injection systems to upgrade classic Jeeps that were made in model years before on-board computers were standard. Howell Engine Developments produces wiring harnesses that don't require Jeep owners to be electricians or computer programmers to successfully install in their classic Jeeps. Classic Jeeps can now access the increased fuel economy and heightened performance of an ECM controlled fuel injection system without the Jeep owner accessing headaches while installing the upgrade.
