so guys heres the verdict after spending 3 days in workshop mechanic service my carburator than opens the petrol trunk , the trunk was full of zang hence it always ruined fuel filters so he clean the tank aswell the lines were fine so breathing pipes were fine now moving towards the next step that is fuel pump surprisingly fuel pump was working aswell so we were back to zero because every thing was working fine so i went to shafiq mour karachi theres a guy who only deals with fuel pump all kind of fuel pumps asking his opinion and let him check my fuel pump , the guy said theres a problem in cultus fuel pump it always go dead after certain time periods doesnt matter how much u run on petrol or cng theres a company fault in cultus anyways coming back to my fuel pump he said pump is not working 100 percent when it gets hot it stop working theres a coil inside thats burn i ask him whats the solution he said if u put another one inside u will be coming to me after few months the best solution is to put a external fuel pump theres are 3 brands , china made , korean made and made in usa now the basic difference btw all of them is there inside structure china and usa ones based on point and he said the point gets dust often so he wasnt in the favour of china or usa ones also they make lot of grr grr sound so he recommend korean one which seems good to me and sound was unbelievable low , just to confirm his statement i met few other guys in the market and ask there opinion and all seems to be in favour of external and the korean brand hence i went for korean one after spending another hour there the guy fixed it perfectly and i went to my mechanic again for final setup of my petrol tank and 8 o clock my car was running fine and smooth on petrol mashallah the pick comes back and i am utterly satisfied with the performance though i was double mind to put the external one or not but it turn out to be okie fingers crossed , here are few tips for the users that use petrol more often u guys need to keep eye on your fuel filter atleast once a week because if your petrol tank is dirty it will choke carburator and lines and that will lead u to do all this lenghty work i been go through also please dont use any petrol pump petrol try to go for a good reputation petrol pump , and if u can afford try putting 1000 rupees worth of high octane every now and than last but not the least make sure that u run your car on petrol and make sure your pump stop works when your car running on cng , i hope this helps .
