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.

Parts used in this section:
Mac valve
Brass street tee - 1/4 NPT
Breather fitting - 1/4 NPT
Brass check valve (female to male) - 1/4 NPT
Vacuum filter - 1/4 NPT
Brass pipe (2" long) - 1/4 NPT
Brass street elbow - 1/4 NPT
Brass pipe union fitting - 1/4 NPT (x2)
Brass barbed elbow fitting – 1/4 NPT-male to 3/8" barb

Time:
25 minutes

Tools:
Wrenches
Pliers
Thread-sealing tape

 

  1. All metal-to-metal connections will require thread-sealing tape. Wrap the tape clockwise around the fittings. Do not apply thread sealing tape to the fittings that will be attached to the vacuum filter.
     
  2. If not already in place, then attach the muffler to the vacuum pump exhaust port. The muffler is not included in the EVS kit because it is part of the vacuum pump. Vacuum pumps purchased at VeneerSupplies.com include an exhaust muffler.
     
  3. Carefully attach a brass pipe union fitting to the pump's vacuum intake. Be certain you attach this part to the vacuum port. The exact location of this port will vary from one pump model to another. Do not assume that the pictures in this article are showing the vacuum port location for your pump as it can vary from one model to the next. Read the directions that came with your pump to determine which of the ports is for vacuum.
     
  4. Close Up - Filter on Pump Connect the vacuum filter to the brass pipe union. Vacuum filters have an arrow indicating flow direction. Note that the direction air flow should be toward the pump. Remember that the filter head is made from a composite plastic and is soft. Avoid over-tightening the filter. When the filter just becomes snug, then continue tightening until the filter is in the vertical position.
     
     
  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 street tee to port 2 on the Mac valve. Note the final position of this fitting on the Mac valve as shown below.
     
  9. Attach the 2" brass pipe to the straight side of the street tee.
     
  10. Attach the another pipe union fitting to the remaining open port on the street tee.
     
  11. Attach the street elbow to the brass pipe. Note the direction that the elbow fitting is pointing when tight. It should be pointing in the same direction as the pipe union fitting.
     
  12. Check to make sure your final assembly looks like the one shown below.
     
  13. Attach this assembly to the vacuum filter. When the assembly is snug, the street elbow fitting will be at the top of the pump and the barbed elbow will be at the bottom.

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