Checks and inspections

CHECKS AND INSPECTIONS

Thoroughly clean the gauze filter.

Water in the filter is particularly damaging to the pump as it provokes internal oxidation. Carefully check the operation of the pump if the fuel is polluted with water. Also check the efficiency of the pump power supply contacts as any oxidation could cause a drop in voltage at the tips reducing supply and leading to the formation of air bubbles and a reduction in injected fuel.

ATTENTION: When substituting the pump remember that it should come filled with protective oil and with the connections closed by suitable plugs. During installation it is not necessary to drain the pump as the oil in it will be burned by the engine. If the pump is drained of its protective oil it must be installed within two weeks in order to prevent a film of dried oil forming on the manifold of the motor which would render it inoperative through lack of electrical continuity.

FUEL FILTER

The fuel filter is located under the platform in front of the fuel tank. It is of the paper tuype with a high degree of filtering power, an indispensable quality given the sensitivity of the electroinjectors to foreign matter. On the outer casing of the filter is an arrow which indicates the direction in which the fuel flows and therefore the correct assembly position.
