2. Install the suction oil line (from the the tank to the canister filter) :
a. Refer to Figures 4A, 4B, and/or 4F.
b. Prepare a piece of 1/2" O.D. copper tubing (user-supplied) which will function as the pick-up
line from the tank to the canister filter. This copper tubing must have the following
specifications:
• The tube must be one continuous piece of 1/2" O.D. copper tubing with no kinks
or fittings.
• The tube is to slant up from the tank to the pump with no loops or high points to
trap air.
c. Locate the 2" MPT x 1/2" FPT x 1/2" FPT duplex, slip-thru hex bushing (which will
eventually be installed into one of the 2" openings on the tank). Note that the fitting is
marked "S" for suction and "R" for return.
d. Install the 1/2" MPT x 1/2" slip fitting into the "S" side of the 2" duplex slip-thru hex
bushing.
e. Install the 1/4" MPT x 1/4" compression fitting into the 1/2" x 1/4" brass bushing.
f. Install the 1/2" x 1/4" brass bushing into the "R" side of the 2" duplex slip-thru hex bushing.
g. Measure the height of the oil tank (from the bottom of the tank, NOT the floor) to the 2"
opening that you are going to use for the supply oil line. Deduct 12" (305mm) from this
measurement and transfer this new measurement onto the 1/2" O.D. coppper tubing.
h. Remove the locking nut and ferrel sleeve connector from the 1/2" slip fitting, and slide them
over the copper tubing.
i. Slide the 1/2" O.D. copper tubing through the 1/2" slip fitting, which is installed in the "S"
side of the 2" hex bushing.
j. Install the screen into one side of the 3/4" check valve (making sure the arrow is pointing
away from the screen assembly).
k. Install the 3/4" x 1/2" brass bushing into the 3/4" check valve.
l. Install the 1/2" MPT x 1/2" flare adapter into the 3/4" x 1/2" brass bushing.
(e.) Prepare the canister filter for installation (continued):
• Remove the plug from one of the 1/8" gauge ports in the canister filter and install the vacuum
gauge. Seal the threads of the gauge with Permatex #2 non-hardening gasket sealer.
• Install the 1/2" threaded pipe adapter into one side of the 1/2" ball valve.
• Install the 1/2" MPT x 1/2" flare adapter into the other side of the ball valve.
• Install this assembly into one side of the 1/2" brass tee.
• Install the assembled 1/2" tee into the 3/4" x 1/2" brass bushing, which is installed in
the inlet port of the canister filter. Make sure that the 1/2" flare adapter is pointing down.
• Install the canister filter assembly onto the 1/4" brass street elbow as shown in Figure 4E.
The canister filter must be installed with the arrow pointing towards the pump (direction of
oil flow).
• Install the 1/2" x 5" brass nipple into the top side of the 1/2" brass tee assembly.
• Loosely install the 1/2" brass cap onto this nipple. DO NOT tighten the cap at this time.
