Installation Notes: Port/connection size M18 X 1.5 center thread. The fuel filter is connected in series on the pipeline between the fuel pump and the inlet of the throttle body. There are 4 ports, two inputs and two outputs. We have provided two plugs and two plugs, which must be plugged with Teflon tape before use, and then installed on the filter and tightened to prevent port leakage. When installing the water separator and filter, put down the nylon collection bowl. When installing the filter, use a tool to tighten it. Please add oil to the filter before installation. Precautions: If you don't have one of these diesel rotary filters, please don't fall into the water. The input port and output port can be on the same side or on the other side to meet your various needs. The outlet at the bottom allows you to discharge excess dirt and water without disassembling the components. Please note that the bowl is reusable, don't throw it away unless it is broken. Regular inspection and replacement.
