I just got my autometer Pro Comp Oil and Boost guages with the stainless steel hoses. The end to the boost pressure guage is much to large to hook to one of my vacuum lines. My shop wants to tap into the manifold and thread in the line to get a stable and direct line to boost pressure. I dont know what to do. does anyone know of a better way, just the idea of drilling my manifold doesn't seem like the best idea to me but it may be. Does anyone know what the best course of action is....thanks
