Cleaning Fuel Filter Water Trap

When water and sediment are visible at the sight-glass (B), shut off the engine and open drain cock (A). Trap the contaminated fuel as it emerges in a suitable container. Then close drain cock (A) again. To clean the filter further, proceed as follows:

Unfasten sight-glass (B).

Remove filter insert (C) and clean it thoroughly in clean diesel fuel. When the insert has been washed between 5 and 10 times, throw it away and use a new insert.

Once the filter has been cleaned, re-assemble it, reversing the removal procedure.
