Hesitation/Stall question

That does not look like fuel line....I would put the garden hose back in the front yard and get some fuel line, then reevaluate (its probably vapor locking).​

Not a garden hose this is a fuel line. It is clear so I could see flow or any issues. But it is only temp. until I resolve the issue. I have the standard line that was removed to place back on it when done.
