Figure 4K - Pressure Relief Oil Line Back to the Tank

Installing the Pressure Relief Oil Line Back to the Tank

ATTENTION: It is critical that you adhere to the following specications for plumbing the pressure relief back

to the tank.

The metering pump requires the installation of a pressure relief oil line back to the tank that you are pulling oil

from as shown in Figures 4F, and 4J.

• The pressure relief will open and relieve pressure if there is a restriction in the pressure oil line,

clogged nozzle, etc.

Be sure to use Permatex #2 non-hardening gasket sealer to seal every threaded tting. DO NOT use teon tape or

teon pipe dope compounds.

1. Refer to Figure 4K.

2. Remove the plug from the relief port on top of the metering pump head.

3. Install the 1/8 NPT x 1/4 tube compression tting in the relief port on top of the metering pump head.

4. Install 1/4" O.D. copper tubing (user-supplied) from the pressure relief port back to the oil tank.

Refer to Figure 4J as needed.
