It's not liquid sucrose. It's mostly water in fact so 3/4 cup maple syrup is not just like 3/4 cup table sugar. The truth is that to get enough maple flavor to even taste will take a tremendous amount of syrup. Thai may work for adding to secondary, but not for priming. Priming sugars should only be used to carbonate beer, not add flavors. If you want maple flavor use extract.
I recently brewed a smoked maple barleywine. I used maple syrup at the end of the boil, but was not happy with the level of maple flavor at the end of fermentation. Primed 5 gallons with 1 1/4 cups maple syrup. Carbonated nicely and added noticeably to the maple flavor.
