Well atlast the wait is over and got the fuel pump + fuel filter replaced.The fuel tank of liana is pain is *** to remove.Went to Suzuki Kazim Motors by 11am and went back by 5:30pm.Mechanic charged me Rs 1000 for fuel filter replacement.
Fuel pump bought by me from Kohenoor Autos for Rs 4500 Japan Made OEM Denso.And now no more shut down.But one thing that they didnt remove the whole tank just lower it from one side and putted the new pump + filter.
The old filter was clogged like hell that some one added mud in the tank.Will post the pics of old fuel pump and fuel filter for reference.
