A–case of a fuel nozzle;
B–top sealing ring of a fuel nozzle;
C–bottom sealing ring of a fuel nozzle; 		D–fastening bracket;
E–fuel highway;
F–element of fastening of a fuel nozzle

PERFORMANCE ORDER
1. Remove pressure in fuel system.
2. Remove a weight wire from the accumulator.
3. Weaken the collars, fixing a hose connecting a measuring instrument of a stream of air and an inlet collector, and remove a hose located over a head of the block of cylinders.
4. Unscrew connecting nuts and disconnect submitting and returnable топливопроводы from the fuel highway (see fig. Fuel highway).
5. Disconnect a vacuum hose from a regulator of pressure of fuel.
6. Disconnect electric sockets from fuel nozzles. Release a plait of wires from fastening brackets on the fuel highway.
7. Unscrew bolts of fastening and remove the fuel highway together with fuel nozzles from an inlet collector. Remove the bottom sealing rings from fuel nozzles.
8. Take brackets of fastening and remove fuel nozzles from the fuel highway. Remove the top sealing rings from fuel nozzles (see fig. Fuel highway and fuel nozzles).

Installation

PERFORMANCE ORDER
1. At installation of fuel nozzles check that its fixing bracket was combined with the corresponding ledge.
2. Before installation of a fuel nozzle establish a new top sealing ring, previously having greased it with a thin butter layer (see fig. Elements of a being self-leveled back suspension bracket).
3. Installation of the fuel highway with fuel nozzles is made in sequence, return to removal taking into account the next moments.
4. At installation it is recommended to replace the bottom sealing rings of fuel nozzles.
5. At installation apply a thin film engine oil on the bottom sealing rings of fuel nozzles.
6. Connect fuel hoses to the fuel highway. Thus keep in mind that the toplivopodayushchy hose fastens to the bottom branch pipe of the fuel highway.
7. Tighten bolts of fastening of the fuel highway to an inlet collector the demanded moment.
