No, don't remove it at the filter, remove it where it attaches to the metal line. That way you'll have a length of fuel line that you can hold and direct away from the vehicle/engine (or into an empty container).
You should see fuel squirting. I don't think it will be steady, but never tried before. You should see fuel, at least.
If it's not flowing, you've got a fuel flow problem. It could be a vapor lock like others have suggested, it could be a valve getting closed in your greasecar kit like you suggested, or it could be a clogged fuel filter/line.
Difficult to determine at this point.
