I have: new carb, fuel filter, fuel pump,new clearwater head. I have noticed that my 86' 2.6 is not getting much vacuum. with the truck idling, I pull off a hose here and there, and there is no difference in engine sound. I know that I was leaking brake fluid into my floorboard and I replaced the brake master, and no more leaks. But i wonder if the fluid ate away at the internal diaphram and is causing a major vacuum leak
