Toyota Corolla 2009... Check engine light is ON and indicates P0440 and P0442 (Evaporative emission, small leak). The repair requires introducing smoke in the fuel line to detect the leak but then no mechanic seems to have capacity of handling it in PortHarcourt. Can anyone be of assistance?

Smoke into the fuel line or evap line you meant.

There are other trouble shooting process used in diagnosing this kind of code.
