i swapped my car's engine d15b3 carby, with d15b3 Efi one but installed the intake and carburetor of original engine,
and a small electronic pump(china) is used to supply fuel to carby.
Now the issue is that the car has high pick , and drinks 1 liter of fuel for every 5-6 km.
The engine is in good condition ,water dropping exhaust on CNG,No oil reduction.
I think it?s the fault of Electronic fuel pump (china) that injects more than required fuel to carburetor, causing high fuel consumption and higher pick.
Please guide me.
