Fuel System Leak Test

-- Let the engine run at idle for a few minutes.

-- Do not use accelerator and then stop the engine. The fuel system bleeds itself.

-- Check the entire fuel system for leaks.

-- Replace the affected component if there are leaks in spite of correct tightening specifications.

-- Perform a road test fully depressing the accelerator pedal at least one time.

-- Check the high pressure system again for leaks.
