Related Parts and Hardware

The in-line filter is disposable. It is mounted on flexible hoses using hose clamps. When replacing, it is worth checking the condition of fuel lines for cracks.

⚠️ Installation Warning

This filter has a flow direction and different port diameters (5/16" inlet, 3/8" outlet). Reverse installation is difficult due to diameter differences, but forcing hoses can lead to damage or leaks. Always pay attention to the flow arrow on the housing!

Part Role in the Machine and Failure Diagnostics

Filter 320/A7170 cleans fuel flowing through the supply line.

  • › Engine stalling (blockage in filter).
  • › Power loss (restricted fuel flow).
  • › Visible debris in transparent housing (needs replacement).
  • › Air entering system (leak at clamps).

🔧 Expert Guide: Key Installation Tips

  1. Arrow: There is an arrow on the filter housing indicating the direction of fuel flow (from tank to engine). Reverse installation will block the flow.
  2. Clamps: Use good quality hose clamps. Old, rusted clamps may not seal the connection, causing air intake.
  3. Cleanliness: When removing the old filter, be careful not to let dirt from the hoses get into the clean side of the system.

Technical FAQ and Trivia

Why do the ports have different diameters?

The diameter difference (5/16" inlet and 3/8" outlet) is a safeguard against incorrect installation (Poka-Yoke). This prevents the filter from being connected in reverse, which could result in lack of filtration or flow blockage.

Is this a main filter?

In some machines, it acts as a main filter, but it is often used as a pre-filter or additional filter on the supply line, working with a water separator.

Trivia about In-Line filters

In-Line filters are extremely simple in design but very effective. Thanks to the transparent housing (in some versions) or ease of disassembly, they allow for a quick visual assessment of the quality of fuel flowing from the tank.
