What symptom does gasoline pump strainer jam have?

What symptom does gasoline pump strainer jam have? Oil pump filter manufacturers for you to introduce it:

Gasoline pump filter screen jam, gasoline filter jam and different degrees of nozzle jam can also cause insufficient oil supply. In addition, the fuel pressure regulator on the filter block, resulting in poor return oil, fuel system pressure will cause too high, resulting in the mixture is too thick. A mixture that is too thin or too thick can cause the engine to run low and cause a shock. Undermixing: the undermixing may be considered to be the cause of the phenomenon if it is not felt on the level road or to a lesser extent on the road, but is obvious or heavy on the uphill.

Mixed gas is too thick: if when driving refueling, feel the acceleration is slow, serious when the car shrugs, driving after refueling and feel strong power, this phenomenon is generally due to the mixture is too thick.

How to deal with the problem: firstly, make a preliminary analysis to determine whether the phenomenon is caused by fuel system problems. If it is determined to be the problem of fuel supply system, the pressure of fuel supply system and gasoline pump should be measured. On the oil path between the fuel pressure regulator and the fuel injector, a tee is connected to the fuel pressure gauge, an air filter is installed, the engine is started, and the pressure of the engine oil supply system under idle, medium and heavy load conditions is tested. Then change the throttle opening, the fuel pressure gauge reading should change with the throttle opening changes, that is, with the throttle opening increases the pressure value increases; Follow the throttle to open.
