The air will travel up the intake and it will reach your throttle body. Most fuel pressure regulators use a diaphragm and spring combination within its housing. Also a return fuel line from the fuel pressure regulator.

These clogs prevent sufficient fuel from reaching the engine causing symptoms like a loss of engine power low fuel economy engine. Symptoms include sputtering at high speeds or engine not starting at all. Kia for example issued a service bulletin 058 dated November 2012 that the Fuel Injection Induction Cleaning Flushing is not a Kia.

This information should be in your owners manual. Next most common problem is the fuel pump failing. Also with a vacuum source on the top side of the diaphragm.

The throttle body is a circular valve thats located in between your air filter and Intake Manifold. There is a main fuel line from the fuel tank to the fuel rail. Some manufacturers advise owners that normal operation will result in a significant amount of oil.

This return line is located downstream of all the injectors. A clogged fuel filter will have high pressure on its input side and low pressure on its output side. Just because your car is consuming oil that doesnt mean its burning it in a harmful way.
