I have read on here that alot of the trucks are taking off the expensive pain in the rear to repair factory carbs. I know that I would have to add a block off plate and a Electric fuel pump. My Question is how will the Weber affect my current MPG? I bought a Weber carb with the adapter plate. The 34G. As of right now I get about 28MPG in the city........Its a small 2.0 with a 5 speed.
