Phenolic is very hard, but can be shaped using common woodworking tools and techniques. If you start with the correct thickness of phenolic, the seal surfaces are already nice and smooth ready to seal up tightly. Metal casting is outside the capabilities and tooling of most DIYers.
I'm going to suggest that if the wiring and a dead ECM are the only issues you have, you might see what jeep clubs are in your area. Someone in the club might be willing to help you resolve your issues (have beer available) and not have to go through changing to a carb. That said I have nuttered my 4.2 and changed to a Weber carb - runs great. Good luck which ever way you decide to go.
I finally received my intake and got it installed. I have the carb in place. Anybody have any good diagrams of how to run the vacuum hoses? My Chilton's manual doesn't have the best diagrams and photos, and since it was previously fuel injected, I don't really have a reference point from before. Come to think of it, a good picture under your hood may be just as good as a diagram.
Thanks in advance.
Thanks in advance.
