Features: 1.Fuel pressure test 2.Fuel flow test 3.Engine intake manifold vacuum test 4.Backpressure in exhaust manifold test 5.Various connectors to fit various vehicle models Specifications: 1.Range of fuel pressure:0~800Kpa 2.Range of fuel flow:0.5~3L/Min 3.Range of engine vacuum:-100~0Kpa 4.Range of backpressure:0~60Kpa 5.Weight:3.3Kg 6.Dimensions:400mmx315mmx95mm Operation procedures: 1.Fuel system pressure and volume test CAUTION:Do not smoke or work near an open flame when work- ing on fuel system inspection. Observe fuel system safety precautions when connecting and disconnecting the pressure gauge.It is advisable to disconnect the battery ground before opening any fuel system fitting.Then reconnect the cable to run the engine for testing.Use this pressure/flow gauge to test fuel system,it is unnecessary to road test vehicle when it is necessary to test fuel volume output.We can check the volume output by the pressure/flow gauge while the engine idle. 1.1.Remove the gas cap to relieve air pressure in the fuel tank.Then relieve fuel system pressure at the station between the fuel input line and the fuel distribution pipe where we are going to connect the gauge.Connect the pressure/flow gauge with a suitable fuel pressure test adapter. 1.2.Start the engine and let it idle,note the pressure gauge and the fuel flow meter.As a general rule,fuel pressure should read about 43psi(300kpa);the fuel flow should read 2 liter/Min.But the pressure and the flow are different from various vehicle models.It should meet OEM requirements,and it should be looked up from the vehicle service manuals. 1.3.Disconnect the vacuum line at the pressure regulator,and plug the vacuum hose.Fuel pressure should rise as vacuum line is disconnected.As a general rule,the pressure should rise 4 to 6 psi from the regulated reading.If the pressure do not rise as vacuum line is disconnected.Connect a vacuum gauge or hand vacuum pump with gauge to the disconnected hose,and start the engine and let it idle.Check the vacuum gauge reading: a.If vacuum is shown,reconnect the vacuum hose to the regulator. Wrap a shop cloth around the fuel return hose and lightly pinch off the hose,the pressure should rise;if not,the fuel pump may be defective;if dose,the regulator may be defective. b.If no vacuum is shown,inspect pressure regulator vacuum lines for improper routing,loose connection,and damaged or deterioration. Replace it as required.If the hose is good,check the cutoff solenoid if the engine has or for an engine problem.Some engine fuel pressure regulator is controled by a cut off solenoid valve at coolant temperatures above about 211°F(105°C) or intake air temperatures above about 170°F(80°C).Disconnect the vacuum hose at the pressure regulater.Connect a vacuum gauge or hand vacuum pump with gauge to the disconnect hose.Start the the engine,and warm it to normal operating temperature (electric cooling fan on).Intake air temperature must exceed about 176°F(80°C).Check the vacuum gauge reading.If vacuum is shown,test the pressure regulater cutoff solenoid valve as described in the vehicle service manuals. 1.4.Start the engine and let it idle,as a general rule,the fuel flow should read 1.0~2.0 liter/Min.If the flow reading is under 0.6 liter/Min,the fuel volume output from the pump is insufficient.Some promblems such as lack of power,rough running,engine surges or any fuel -pressure regulated driveability promblems will be appeared.If the fuel flow is too low,the fuel filter,pump inlet filter or the pump may be bad.Wrap a shop cloth around the fuel return hose and lightly pinch off the hose,the fuel pressure should rise about 15psi(100kpa),if it dose,the filter or the pump inlet filter may be restricted;if it not,the fuel pump may be bad.Some vehicles such as some moddles of CAMRY ,there are no regulator at the delivery pipe.In order to check the fuel volume output from the pump,disconnect the intake fuel pipe and connect the pressure/flow gauge,then put the outlet hose of the gauge in a keg.Connect the fuel pump relay with a short wire to run the full pump.Punch the outlet hose of the gauge gradually with the fuel pliers while watching the pressure gauge.The pressure should rise to the station below normal about 0.5 psi then keep it steady and reading the flow meter.The fuel volume should meet requirements. 2.Fuel Pressure Regulator Test For some engines,vacuum to the pressure regulator is controlled by a cutoff solenoid valve at coolant temperatures above about 221°F(105°C)or intake air temperature above about 176°F(80°C). 2.1.Inspect pressure regulator vacuum lines for improper routing,loose connections,and damage or deterioration. 2.2.Disconnect the vacuum hose at the pressure regulater.Connect a vacuum gauge or hand pump with gauge to the disconnected hose. 2.3.Start the engine and let it idle.Check the vacuum gauge reading: a.If vacuum is shown,continue testing. b.If no vacuum is shown,test the pressure regulator cutoff solenoid valve as described in the vehicle service manuals. 2.4.Remove the vacuum gauge or pump/gauge and reconnected the vacuum line to the pressure regulator. 2.5.Check the pressure gauge,fuel pressure should be about 43psi(300kpa).But the pressure is different from various vehicle models.It should meet OEM requirements as described in the vehicle service manuals. 2.6.Disconnect the vacuum hose at the regulator,fuel pressure should rise about 4 to 6 psi from the regulated reading as vacuum hose is disconnected. 2.7.If pressure does not rise in step 6,wrap a shop cloth around the fuel return hose and lightly pinch off the hose,while doing this,watch the pressure gauge,the pressure should rise;if does,the pressure regulator may be defective;if not,the fuel pump may be defective. CAUTION:When pinch off the fuel return hose,do not let the pressure rise too high,such as 100psi(700kpa),or the gauge and the fuel hose will be damaged. 3.Fuel Static Pressure Test Start the engine and let it idle for 2 to 3 minutes,then turn the engine off,and check the pressure after 10 minutes.Fuel pressure should stay at about 25 to 30 psi or more.If the system does not hold pressure,it may be caused by: faulty fuel pump check valve a leaking hose coupling at the pump a leaking fuel pressure regulator an injector that is stuck open Check for the leakage at fuel pump,injectors or at the regulator. 3.1.Connect the pressure/flow gauge at a suitable station after fuel filter before fuel regulator.Start the engine,let it idle for a minute,then turn off the engine.Wrap a shop cloth around the fuel return hose and lightly pinch off the hose with the fuel hose pliers before the pressure drop to too low.Check the pressure gauge reading: a.If the pressure do not drop any more,the leakage may be at the regulator. b.If the pressure keep droping,continue testing with step 3.2. 3.2.Disconnect the fuel hose pliers,and restart the engine,let it idle for a minute,then turn off the engine.Wrap a shop cloth around the fuel outlet hose of the pressure/flow gauge and lightly pinch off the hose before the pressure drop to too low.Check the pressure gauge reading: a.if the pressure do not drop any more,the leakage may be at one of the injectors. b.If the pressure keep droping,the leakage may be at the fuel pump. 3).Relieve system pressure,remove the tester,and restore all the connections. 4.Air lock in fuel system test Air lock may be caused by: insufficient gasoline in the fuel tank a restricted pump inlet filter bad gasoline in hot condition Connect the pressure/flow gauge and start the engine,watch the pressure and flow,if they are surging quickly,there may be air in the system. Stop the engine,disconnect the fuel pump fuse or the fuel pump relay,then restart the engine again,keep waching the flow meter.There may be balls of air become bigger as fuel pressure drops. While do this,pay atention to that if the gasoline is dirtyed,and if there are drops of water in the gesoline. 5.Exhaust system backpressure test for restricted exhaust or catalytic converter The exhaust oxygen(O2) sensor can be removed from the manifold on most engines for access to the exhaust system for testing.On some engines,the sheet meltal heat shield must be removed for easy access to the sensor.On some engines,it may be easier to test exhaust backpressure by removing the EGR valve.Be sure to plug the EGR inlet to the intake manifold during testing. NOTE:during removal.Access to the O2 sensor may be difficult on some vehicles.If the engine has air injection,you may be able to remove the air injection check valve or tube and connect the pressure gauge in this location.Be careful not to damage the check valve CAUTION:Remove the exhaust oxygen(O2) sensor carefully to avoid damaging the threads on the sensor or in the manifold. 5.1.Remove the O2 sensor or the EGR valve and install the backpressure tap (E301)into the manifold. 5.2.Start the engine and let it varm up until the coolant temperature sensor(CTS) reading is at least 85°C(185°F) or until the cooling fan turns on at least once. 5.3.Connect the pressure gauge with the adapter(V/E201) to the backpressure tap,and take the backpressure reading at 2500rpm as soon as quickly.If it is too long,the adapter(V/E201) will be damaged by the heat.As a general rule,backpressure should not exceed 2.0psi.Most vehicles in good condition will operate with exhaust backpressure from 0.5 to 1.5 psi.Many technacians feel that backpressure above 1.5psi may cause driveability promblems. 5.4.If exhaust backpressure is suspected as the problem for a no-start condition,perform the backpressure test while cranking.In some cases,it may be possible to get an engine started after removing the O2 sensor or air injection check valve to relieve backpressure. If the backpressure test indecates a restricted exhaust,check the following areas: A restricted muffler. A restricted catalytic converter. A collapsed or bent exhaust pipe. If tests indicate the converter is restricted and should be replaced,determine the cause of the failure to advoid future converter damage. Among the items to check are: Use of leaded gasoline. Prolonged rich operating due to fuel system control problems or misfiring spark plugs. Improper operation of the air injection system. High oil consumption due to mechanical wear. 6.The vacuum in intake manifold test The vacuum in intake manifold influenced by problems of the engine.So we can found many engine problems by inspecting the vacuum in intake manifold.Connect the vacuum/pressure gauge with adapter V201 to a suitable vacuum hose to intake manifold. Start the engine and let it idle.As a generul rule,the gauge reading will stay at about 17 to 21 psi.The various problems of the engine can be found as described on the last two page. 7.Finish inspection When finish inspection,hang up the pressure/flow gauge and put the hose of the gauge in a container so that the fuel in it flow out, then clean it with a clean shop cloth.Inorder to keep it work well, it is necessary to keep the o-rings clean and apply a light coat of oil to it before use. How to use the adapter F101, F102, F105 According to the picture below, you will know how to use the adpter easily. Disconnect the bolt in fuel filter or in delivery pipe. Choose a suitable adapter from F102~F105, install the adapter without sealing washers to the filter or the delivery pipe use the bolt disconnected, the torque should smaller or the adapter will damaged. After this, connect the adapter other side to the quickly adapter of the pressure/flow gauge, the fuel flow direction should fit the pressure/flow gauge. Connect the fuel pipe to F101, then connect F101 other side to the quickly connecter of the pressure/flow gauge, the fuel direction should fit the gauge.
