engine running and reduction of both noise level and dangerous emissions.
     The assembly is composed of :

- downtake pipe (1);
- pipe and expansion chamber (8);
- intermediate pipe (4);
- silencer (7).

For vehicles equipped with injection system the downtake pipe is equipped with catalyst (11)

which has the purpose of pollution emissions reduction.

PARTICULARITIES

The electric fuel pump (picture 2) is fixed on the tank,being immersed in fuel and is commended

by the computer,by means of the fuel pump relay (R1). When contact is on,with the key in the
position M (engine),but without starting the engine,the pump will be fed with electricity only for
3-4 sec.The pump will permanently flow only when the computer is receiving signal from the
rpm sensor and must ensure a minimum flow of
1 - 1,1  l/min.and a pressure of 1-1,1 bars at 12 V. The cause of an insufficient flow may be the
low feeding tension of the pump or a dirty fuel filter.
  In case it is defective the pump is not to be repaired but replaced.

ATTENTION!

In the feeding system,the fuel remains under pressure even after stopping of the

engine; in case of hoses disconnecting,place a cloth material next to the connection so
that fuel does not reach the hot areas of the engine.

    The flow measurement is done as follows:

- connect the return from the injector valve body to a hose which will flow fuel in a

gauged vessel of 2000 ml;

- feed directly the pump during 1 minute,starting the engine or by  by-passing the connector

30 and 87 of the fuel pump replay (R1),with the engine stopped and contact off.
