高壓泵柱塞壓力測試工具的方法：
A. 泄壓:先拔下燃油泵保險絲、繼電器或燃油泵插頭，然后啟動發動機，待發動機自行熄火后測量。B.安裝燃油壓力表:將燃油壓力表與進油管串聯，帶測壓口的車輛將燃油壓力表與測壓口連接。拆卸油管時，在油管接頭下方放一塊毛巾或棉布上。C壓力表一般安裝在汽油濾清器的出油口或燃油分配管的進油口。
完成上述準備工作，啟動發動機，輕踏油門，觀測壓力由低到高過程，查看油泵在全負荷狀態下是否出現滲漏問題。
Method of high pressure pump plunger pressure test tool:
A. Pressure relief: first unplug the fuel pump fuse, relay or fuel pump plug, then start the engine, and measure after the engine shuts down by itself. B. Install the fuel pressure gauge: connect the fuel pressure gauge in series with the oil inlet pipe, and connect the fuel pressure gauge with the pressure tap for vehicles with pressure taps. When removing the oil pipe, put a towel or cotton cloth under the oil pipe joint. C the pressure gauge is generally installed at the oil outlet of the gasoline filter or the oil inlet of the fuel distribution pipe.
Complete the above preparations, start the engine, lightly step on the accelerator, observe the process of pressure from low to high, and check whether the oil pump leaks under full load.
