This house-side valve—usually a ball valve—may be located where the pipe first enters the house or farther down the line, but it will always be located before the first appliance. If iron pipe is transporting the gas, it’s often black; this differentiates it from similar-shaped, gray galvanized water pipe.
May 11, 2020 Roadblock #2: Restrictive Factory Turbo Inlet Manifold. It can be argued that the turbo inlet manifold on the LB7 Duramax was an airflow choke point, but on the LLY there is absolutely no denying it. In restricting airflow into the compressor side of the LLY’s turbo, it forces the charger to work even harder to produce sufficient boost.
