Проверка давления шестеренного насоса топливного насоса

Цель: To check whether the fuel pump gear pressure is normal

• The following tools are required for inspection: Сервисное программное обеспечение INSITETM, Фитинги CompuchekTM (номер части 3824844), манометры [0 в 300 фунтов на квадратный дюйм], манометры [0 в 30 фунтов на квадратный дюйм].
• Install the pressure gauge:

Remove the plug at the fuel filter seat inlet and install the CompuchekTM fitting (номер части 3824844) to the inlet of the fuel filter seat. Install a pressure gauge from [0 в 300 фунтов на квадратный дюйм] to the CompuchekTM fitting at the inlet of the fuel filter holder.

• Test high idle pressure:

Run the engine at high idle and observe the fuel gear pump pressure. The gear pump pressure at high idle speed should be no less than 75 фунтов на квадратный дюйм.

• Test gear pressure

When the engine is not starting, install a 0-30 psi pressure gauge to the Compucheck fitting at the inlet of the fuel filter holder. The motor drives the engine to observe the fuel gear pump pressure. The gear pump pressure should not be less than 10 psi when the motor is cranked.
