Howell Fuel Injection Kit for 1972-1993 304, 360, 401 V-8 Jeep/AMC - available in 2 versions OFFROAD and EMISSIONS LEGAL OFFROAD
OFFROAD: This Kit converts any 1972-1993 304, 360, 401 V-8 Jeep/AMC to an ECM controlled throttle body fuel injection system. The remanufactured GM throttle body adapts directly to the four barrel intake manifold, replacing the carburetor. This Kit contains all necessary sensors, wiring harness, ECM, electric fuel pump and runs with the stock Jeep distributor. Great for serious four-wheeling! The ECM installs under the dash. The high pressure fuel pump must be installed in the main fuel line from the gas tank, and bypass fuel returned to the tank. The wiring harness includes a diagnostic connector, and diagnostics are similar to a 1986-92 GM pickup truck.

Are you running 2 or 4 barrel Carburetor?
Are you running the stock Intake Manifold?

Crank Case Ventilation Ring: You will not be able to use your stock air cleaner with the Howell EFI Conversion kit. When removing your old air cleaner on most CJs and YJs you'll notice a hose that hooks into it and then hooks into the back of the valve cover. You will need to retain it so this ring will let you hook up the hose. If it's between the air cleaner and throttle body, We offer the
Valve Cover Recirculation Spacer that fits under the air cleaner and will allow you to reconnect your hose.
