Haha...don't think I'll like diesel tasting. Pela type pump will have to do.I can't get any sleep until you solve this thing !
With the secondary filter (SF) being empty, sounds like the lift pump is doing a fine job of getting all the fuel it can before it starts sucking air out of the SF.
If you're really serious about solving this then close the fuel supply valve on the top of your fuel tank and then remove the inlet hose to the SF. Take the fuel inlet hose in your mouth and suck for all you're worth

If you're not THAT serious about the problem, then put the vinyl hose from your oil vacuum suction pump (Pela type) into the end of the fuel line which you opened up. Wrap the vacuum tube with tape to ensure you've got an airtight seal.
If you can't maintain a vacuum, you've got an air leak in the fuel line, or primary filter, or fittings, or etc, or etc. Take your pick.
Good luck as always.
