Removal

PERFORMANCE ORDER
1. Before separation of fuel-supply lines take off pressure in fuel system as, otherwise, the fuel which is under pressure will intensively follow from fuel system.

Prevention

Close connection by a towel to exclude the fuel spraying caused by residual pressure in a fuel-supply line.


2. Remove the fuel highway together with fuel nozzles.

Prevention

At removal of the fuel highway do not drop fuel nozzles.



Check

PERFORMANCE ORDER
1. Disconnect the socket from a fuel nozzle and measure resistance between contacts of the socket.

Resistance: 15,9± 0,35 Ohms

2. If the size of resistance differs from the required value, replace a fuel nozzle.

Installation

PERFORMANCE ORDER
1. Establish new sealing rings on a nozzle.
2. Grease sealing rings of nozzles with fuel.
3. At installation of nozzles turn them around an axis in one and other parties.
4. Make sure that nozzles are densely inserted into the fuel highway.
