Maintenance Manual for Chery·Windcloud Marelli EFI System
12. Assembly of Steely Fuel Distributing
Pipe
Purpose: to store and distribute fuel to
provide fuel injection system with a fairly
stable pressure environment, to achieve
counterbalance of supply pressure and fuel
feed of each cylinder as well as smooth
engine operation.
Composition: fuel distributing pipe
assembly is made up by fuel distributing
pipe and injector.
Installation requirement: connect fuel
inlet/outlet pipes with rubber pipes and
fasten them down with hoops. The size of
hoops used shall match that of rubber pipes
so as to ensure air-tight connection between
fuel inlet/outlet pipes and rubber pipes.
Failure diagnosis: generally, the probability
for failure occurrence of fuel feeding header
pipe is slim. Mostly, failure is caused by
improper assembling, which leads to leakage
in fuel system, therefore, be careful when
assembling: O-ring oil seal used can not be
reused; when assembling, apply some
lubrication oil as appropriate.
