The gas pressure regulator of the inspection work (Dieselpartsworld) 2016-02-28    

Gas pressure regulator structure
(1) gas pressure regulator on the vehicle inspection
The gas pressure regulator of the inspection work:
By measuring the engine oil pressure meter idling gasoline pressure when running the check, and then remove the vacuum hose on the regulation. When the gasoline pressure should be increased about 50kPa, it should be replaced.
The gas pressure regulator to maintain pressure check
Check the pressure gauge access to fuel lines, with a wire two detection of electric gasoline pump connecting hole short circuit.
Turn the ignition switch, let the electric fuel pump running 10s, then turn off the ignition switch, remove the wire. Observation of the oil pressure 5min, the pressure is the gas pressure regulator to maintain pressure.
If the pressure is lower than the prescribed value, the gas pressure regulator return pipe clamp. Http://www.qcwxjs.com/
If the oil pressure rise, indicates that the regulator has a leak, should be replaced. If the oil pressure remains unchanged, that other parts of the fuel system for leaks.
If the pressure is higher than the specified value, indicates that the regulator vacuum hose leakage. Technology of vehicle maintenance
(2) remove the check the fuel pressure regulator
The inlet pipe and the vacuum hose to check when remove the fuel pressure regulator, then between the two should not be communicated; otherwise, that there is a leak, should be replaced.
