Fuel System Leak Test

Fuel System Leak Test

- Clean all the fuel connections that were removed and installed again with brake cleaner and then dry them.

- Let the engine run a few minutes at idle without pressing the accelerator pedal and then turn off the engine. The fuel system bleeds itself.

- Check the entire fuel supply system for leaks.

If there are leaks even though the correct tightening specification was used, replace the affected component.

- Perform a road test fully pressing the accelerator pedal at least one time. Then carefully check the high pressure areas for leaks again.

• If there is still air in the fuel system, the engine may switch to emergency mode during the road test. Turn off the engine and erase the Diagnostic Trouble Code (DTC) memory. Then continue the road test.
