@Xulfiqar hope you are doing great and well
i have the same problem with cultus 2006(non-efi) recently purchased. fuel pump was installed under the bonnet.
recently i replaced and restored it to factory setting. installed Leppon fuel pump in the tank.
issue i faced tht it stop working after driving of around 25kms, i diagnosed by my self that some tick tick sound is coming from tank on giving self.
2ndly the battery charging light in dim status is continuously showing on while engine is running, whether u cut of the fuel pump wiring from back seat.
3rd what is the position of fuel filter in cultus 2006, its just beside the fuel tank or there is no need of fuel filter as fuel pump already have in the tank.
can u or anyone from this form, pls address these issues?
Jazak Allah Khair.
