2) Check low pressure fuel supply circuit for fuel
leakage.
3) Start engine and run it at idle speed for about 10
seconds.
4) Stop engine and then check for fuel leakage in each
part, which was serviced.
5) Start engine and run it at 4,000 r/min. for about 10
seconds.
6) Stop engine and then check for fuel leakage in each
part, which was serviced.
