- drain fuel from the filter by unscrewing plug 8 (Figure 6.4.58) in the lower part of
the body;
- prevent fuel spillage, and drain fuel only into a special container;
- unscrew filter 1 from fitting 7 in body 3 and mount a new filter instead, which is
supplied in assembly with gasket 2; lubricate the gasket with engine oil before installing
the new filter
- after gasket 2 touches the mounting platform “A” on body 3, tighten the filter up by
another 3/4 revolution. The additional tightening shall be carried out by hand force only;
- fill the system with fuel;
