WARNING

Installation
6311304H
Installation
When unpacking pump, check for shipping damage.
Report any shipping damage to delivering carrier imme-
diately.
Mounting Pump
1. Apply PTFE thread tape (provided with the pump) to
large thread of bung adapter (9) (2 in. X 1 ½ in.
reducer fitting). Install bung adapter to fuel tank.
2. Assemble suction tube sections by applying ¼ in. to
½ in. wide bead of PVC cement (PN: 260086; white
tube provided with the pump) around the entire
inside diameter of the coupler (see FIG. 1). While
sliding the tube into the couplers turn the tube at
least one full revolution until the tube bottoms out on
the coupler (see FIG. 2, FIG. 3, and FIG. 4). This will
allow the cement to coat the entire surface for the
best possible seal. Allow cement to set for 5 min-
utes minimum before installing pump into tank.
CAUTION
Do not use a curb pump automatic shut-off nozzle
with this pump. Use of a curb pump automatic nozzle
may cause priming problems, reduced output flow,
and motor overheating. If an automatic shut-off nozzle
is required, use Graco part number 260082 (regular)
or 260083 (unleaded) or Catlow, Inc. part number
NCLF-1 (regular) or NCNLF-1 (unleaded).
CAUTION
• Ensure tank being used is clean and free of welding
slag
• Ensure the tank is vented to allow air into the tank
as the fuel is being pumped out. Failure to provide a
vent will cause priming problems
For tanks deeper than 36 in. (914 mm) you will
need a standard 1 in. (25 mm) pipe with 1 in. npt
threads on one end. Suction tubes longer than 60
in. (1.52 m) require a foot valve (Graco Part No.
260217) at the bottom of the tube to prevent loss of
prime.

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 FIG. 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 FIG. 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.

9. Tighten nut on strain relief to form a seal around the
power cable.
10. Reinstall electrical cover (2a) on the pump.
11. Remove 1/2 in. (13 mm) of insulation from wires on
the fuse holder end of the power cable.
12. Attach battery clamps (6a) with red sleeve to red
wire and black sleeve to black wire. Wire must be
crimped to the battery clamp firmly to get a good
electrical connection.
13. Connect red wire with fuse holder inline to positive
battery terminal. Connect black wire to negative bat-
tery terminal.

in. (13 mm) from individual conductor insulation.
4. To remove electrical cover (2a), remove four bolts
(2c).
5. Remove 1/2 in. (13 mm) of insulation from power
wires inside pump electrical terminal cavity.
6. Insert electrical power wire through conduit opening
in back of pump.
7. Using wire nuts (2e), connect wires: green to green,
white to white, and black to black.
8. Replace electrical cover.
If you are installing models 260580 or 260581 skip
this section. These pumps have been factory wired
Power cable can be cut to shorter length if 18 feet
(5.5 m) is not required. Cut to proper length and
proceed with steps 3 and 4.
On 115 VAC and 230 VAC pumps, electrical con-
nections must be made by a licensed electrician per
requirements of local, state, and national codes
regarding class 1, group D installations. Only rigid
conduit with threaded connections should be used.
Conduit opening in pump must be sealed with
waterproof, fuel-resistant sealant. Failure to comply
with this warning could result in injury from electrical
shock.

Operation
311304H 9
Priming Pump
All pump models should prime within 5 seconds after
pump is turned on up to a height of 36 in. (91 mm).
Pumps installed at height up to 5 ft. (1.52 m) may have
difficulty priming. Follow procedure below to initiate
prime. Pumps installed at suction height above 5 ft.
(1.52 m) will have difficulty in holding prime. It is recom-
mended that check valve (Graco part no. 260217) be
added to the bottom of the suction tube to help maintain
prime.
If prime in not achieved in 30 seconds after turning the
pump on use the following procedure to initiate prime;
1. Remove 90° Union Swivel (15) from ¾” Inlet Nipple
(14).
2. Pour fluid being pumped into pump outlet until com-
pletely filled.
3. Re-assemble Union Swivel (15) back onto nipple
(14). Turn pump on. The pump should gain prime in
under 5 seconds.
4. If pump still does not gain prime check for any major
leaks in the system. If no leaks are found then the
pump is mechanically defective and should be
reported to Graco Product Service for disposition.
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 fig. 6). Also, if the pump has
difficulty priming it is easy to remove the swivel and
pour fluid into the pump outlet cavity when assem-
bled this way.
If prime is lost
1. First make sure there are no fluid leaks from the
pump outlet out to the fuel nozzle. Any leaks after
the outlet will allow air to push the fluid column back
to the tank and prime will be lost.
2. If no leaks are detected on the outlet side of the
pump, remove the pump from the tank and inspect
the suction tube and pump inlet for leaks.
3. If the system is leak free and the suction height
guidelines are followed the pumping system should
not lose prime.
Operation
On/Off switch lever (8d) is located under nozzle holder.
Remove nozzle before turning pump on.
1. Move switch lever (8d) on.
2. Insert nozzle into tank and actuate nozzle lever to
dispense fuel.
3. Immediately after fueling turn switch lever (8d) off.
Maintenance
1. Clean inlet strainer (3b) after every 50 hours of
operation.
2. To remove inlet strainer (3b), remove four screws
(3c) and strainer cover (3a). Remove and clean
strainer.
3. If strainer is excessively dirty, clean tank to protect
pump and the equipment being fueled.
4. After cleaning strainer, replace strainer and cover.
Make sure cover seal (3d/7e) is in place.
All guidelines and procedures are based on pump-
ing diesel fuel. If pumping gasoline priming may be
more difficult due to the lift of gasoline dependent
on Reid's vapor pressure of the gasoline and it's
temperature. The lower the vapor pressure and
temperature, the higher the possible lift.
Before servicing, turn pump off and open the
nozzle to relieve pressure.
CAUTION
Do not operate pump dry. Do not run pump for more
than 5 minutes with nozzle closed. Do not operate
pump for more than 30 minutes continuously in 1 hour.
