or, air leak somewhere in the fuel line

Can also be a cracked fuel filter. Same thing has happened to me before.

Try new fuel and run seafoam through it.

Also make sure you have an inline fuel filter in your fuel line 8-12 inches below your fuel pump where your fuel line attaches. I didn't see one in video. Still run sea foam through it because if you've been running it without a fuel filter the sea foam will help alot.

Also make sure your getting good ventilation in your gas tank, if theres not a solid vent in the top of the cap maybe even unscrew the cap a little.
