I am installing fuel pump with vacume pump, for wipers,i know  the in goes to wipers,need help with the out  tube.want to stay with vacume  wipers. the fuel pump is the same as 55/56 birds

On the combination fuel pump and in regard to the vacuum booster hook ups, the outside port goes to the intake manifold or bottom of the carburetor and the inside port goes to the wipers.  ‘Outside’ being the port furthest out from the engine and the ‘Inside’ being the port nearest the engine.
