Okay, in that case you can make it a bit easier, since the belt you have isn't going to work you can use it instead of string. Cut it straight across, route it like the picture and be sure it clears everything. Then back the tensioner off and mark the belt where the cut end is. If you really want to get fancy you could use a couple screws to fasten the ends together where they overlap and test fit it. That would let you release the tensioner and check the final fit before you buy the replacement belt. However I would recommend replacing the pump as soon as practical. Even a salvage yard pump would be better than no pump.
