6.2.3. Dropping pressure in fuel system of the petrol engine, filling of a fuel path

Before getting to work, get acquainted with materials of the Section of the Security measure and the general rules accepted at service of components of fuel paths of internal combustion engines.

Dropping pressure

During implementation of the described procedure only excessive pressure in a path of a power supply system is dumped, at the same time continuing will fill fuel-supply lines fuel to be under some residual superfluous pressure, - before a detachment of fuel lines take the appropriate measures of precaution!
