Denny,
A hose from the side of intake manifold to In/Input side of pump; a hose from the Out/Output side of the pump to the vacuum motor.
Different pumps have different labels/words/markings on the ports, and I have dual-action pumps that have no labels/words/markings
Someone recently posted the logical way to determine how to hook up the hoses:
- Just do it; and, if necessary, re-do it (you have a 50-50 chance of getting it right the first time).
- leave both pipes/hoses at the pump disconnected and run the engine (plug the manifold port). With the engine running, see which port on the fuel-pump sucks (nothing personal). Connect the hose/line to the wiper motor to the sucking port on the fuel pump; the other port gets connected to the fitting on the intake manifold.
Did you rebuild your pump (if yes, tell us the story)?
