I had all three engine cores on the shop floor and was comparing all three engines, I was bored one afternoon. As pointed out, the 4.0 has no fuel pump lobe. I guess you can do as I did once to get a Pontiac wagon home that lost a fuel pump, lash a fuel can onto the luggage rack, duct tape some fuel line staight onto body parts and into the carb and head on down the line....Russ __________________________________________________ Do You Yahoo!?
