Correct. You don't use a balance valve on conventional dual-action fuel pump systems because there is nothing to balance, only one vacuum feed to the wipers as the vacuum section of the fuel pump is in series between the manifold and the wiper motor. The vacuum balance valve is used (55/56 Packard, Cadillac, Buick) because you have two parallel vacuum sources.
