I needed to replace my fuel pump so decided to get the double action vacuum pump type to help with the wipers.
I have made the PCV mod to my otherwise stock 216. I also added dual mc vacuum assisted front disc brakes.
I can think of several options to connect up all the vacuum lines this combo needs.
1. Wipers through the pump to manifold. PCV direct to manifold. Brake booster direct to manifold. So I need a triple-tee at the manifold for this.
2. Like #1 but route the brake booster through the vacuum pump through a T fitting with the wipers. My thinking is that the brakes might get a benefit from the vacuum pump in low-manifold vac conditions?
3. Like #2 for brakes and wipers but gang the pump outlet with the PCV and run a single line to the manifold. This simplifies the routing to the manifold. Some concern of PCV gunk getting into the vacuum pump, but theoretically that shouldn't happen.
The truck is not running yet so I can't test the options. Anyone solve this combo before?
