Build the Sub-Reservoir Manifold
The sub-reservoir manifold is a critical part of the system. Luckily it's very easy to build and consists of only nine pieces. Use the instructions below to get this part assembled easily.

1. Place two passes of thread-sealing tape on each of the male threads from the parts list shown above. Wrap the tape clockwise around the fitting.
2. Attach the brass pipe union to the pump's vacuum intake.
3. Connect the vacuum filter to the brass pipe union. Note that the direction air flow should be toward the pump. Most vacuum filters have an arrow indicating flow direction. Keep in mind that the filter housing is made from aluminum. Because of this, it will not withstand more than one or two loosen and re-tightening opportunities.So be sure you've got everything in its place before you give the final turn.
4. Attach the muffler to the vacuum pump exhaust port.
5. Attach the breather fitting to port 3 on the Mac valve.
6. Attach the check valve to port 1 on the Mac valve.
7. Attach the brass barbed elbow fitting to the check valve. Note the direction that the barb is pointing as shown in the picture below.
8. Attach the brass "T" to port 2 on the Mac valve. Note the orientation as shown below. You don't want to use the vertical end of the "T" shape. It has to be attached to one of the top "T" ends to fit correctly.
9. Attach the brass coupler to the opposite side of the "T". Again, don't attach it to the vertical end of the "T" shape.
10. Attach this assembly to the vacuum filter. When the assembly is snug, make sure the Mac valve is next to the filter body as shown in the picture below.
11. Screw on the brass elbow (male to male threads) to the brass coupler. Make sure it ends up facing opposite the direction of the breather fitting.
12. Check to make sure your final assembly looks like the one shown below.

The final assembly should appear as shown in the picture below.
