Hi Bubba The Fuel Injection Kit would work but will have to be ordered over the phone as it would be a special order and they would have to program the computer for the modifications. Thanks

I own a 78 CJ7 w/ 4.2L and a one BBL Carb. Will this kit fit on a one BBL Carb Intake manifold? My research says No. Thank you, Craig

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.
