Edema has many possible causes: 1  Prolonged standing or sitting, especially in hot weather, can cause excess fluid to accumulate in the feet, ankles and lower legs. 2  Tiny valves inside the veins of the legs can become weakened, causing a common problem called venous insufficiency.
Cars with nitrous-equipped engines can be identified by the purge of the delivery system that most drivers perform prior to reaching the starting line. A separate electrically operated valve is used to release air and gaseous nitrous oxide trapped in the delivery system.
The nitrous solenoid is connected to the nitrous bottle via a steel braided line. The fuel solenoid is plumbed to a fuel source. Once these parts have been installed, its up to the electrical side of the system to ensure that the solenoids open and close properly.ften it is the electrical side of a nitrous system that can be confusing or improperly installed. If these connections are not made correctly, theres the possibility of burnt switches and improperly functioning solenoids.
