SKU HOW CJ258+
Howell Fuel Injection Kit for 1972-1980 Jeep 4.2L CJ - available in 2 versions OFFROAD and EMISSIONS LEGAL OFFROAD
OFFROAD: This kit includes all components to convert a 2BBL CJ or Wrangler Jeep to an
EFI (Electronic Fuel Injected) controlled throttle body fuel injection system. 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 (Electronic Control Module) 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.
EMISSIONS LEGAL OFFROAD: Includes all components above plus a remanufactured 4.3L Chevrolet throttle body to convert a 2BBL CJ or Wrangler Jeep to EFI. The remanufactured GM throttle body adapts directly to the intake manifold, replacing the carburetor. This kit is 50 state emission legal per CARB EO#D452. Many original emission controls are eliminated, which simplifies the under hood area. The ECM installs under the dash. The high pressure fuel pump must be installed in the main fuel line from tank, and the bypass fuel returned to the tank. The wiring harness includes a diagnostic connector, and diagnostics are similar to a 1986-92 GM pickup truck.
Specify the type and year of Jeep when ordering your kit. Sam's Offroad has sold and installed hundreds of these kit's without any problems. After installation, most of your old emission plumbing is eliminated and you'll gain better Fuel Economy & Performance.

Are you running Headers?
Are you running stock Cam?
Are you running stock Pistons?
Are you running 2 or 4 barrel Carburetor?
Are you running the stock Intake Manifold?
Are you running any aftermarket Ignition System? SD? Mallory?
What is the estimated altitude you'll be primarily driving at?
After you place the order, you will receive a phone call to discuss these details for your new Fuel Injection System.
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.
