3. Cut the suction tube so that it is 2 in. (55 mm) from
the bottom of the tank when installed in the tank.
4. Insert gasket (7f) into union nut (1k). If using Graco
supplied PVC suction tube it is not necessary to
apply thread tape before assembly, just screw into
pump inlet (1j). If using metal suction tube (not sup-
plied with pump) then apply thread tape provided
with pump to NPT threads before assembling to
pump inlet (1j).
5. Insert suction tube attached to pump through bung
adapter (9) into tank. Position pump as desired and
tighten union nut (1k) on bung adapter (9).
Mounting Hose and Nozzle
1. Apply thread tape provided with pump to both ends
of hose assembly. Screw ¾” NPT end of 90° union
swivel (15) to one end of hose (see fig. 5).
2. Screw nozzle onto other end of hose and tighten.
3. Start swivel end of 90° union swivel (15) onto ¾”
nipple (14) on pump outlet (see F
IG. 5). Orient the
hose/nozzle assembly to desired position and
tighten swivel fitting.
It is important that the swivel end of the 90° union
swivel (15) is assembled to the ¾” outlet nipple (14)
for proper sealing (see F
IG. 6). If the pump has diffi-
culty priming, it is easy to remove the swivel and
pour fluid into the pump outlet cavity when assem-
bled this way.
