How often can i use this marvel mystery motor & fuel treatment ?

I add at every oil change to gas. I also add standard marvel mystery oil, 1 pint, to crank case 500 miles prior to oil change.

Does this have polyetheramine (PEA)?

None I read or saw in past. Don't have a bottle here as I looked.

Which one of the MMO's will help a whining in tank fuel pump?

Either might help. But that whinnying means fuel pump is about to go.
