PUMP PRESSURE ADJUSTMENT FOR
HEATERS WITH FUEL FILTER INTER-
NAL TO PUMP
1. Remove pressure gauge plug from
fuel pump port marked “GAUGE.”
2. Install accessory pressure gauge (part
number 110380-01) to fuel pump
port marked “GAUGE” (See Figure
20). Do not use bleeder valve port to
check pressure. Bleeder valve port
contains pressure higher than
operating pressure. Setting pump
pressure with gauge in bleeder valve
port will result in wrong operating
pressure.
3. Start heater (See Operation, page 5).
Allow motor to reach full speed.
4. Adjust pressure. Use small flat blade
screwdriver to turn slotted screw at
fuel pump port at top right side of
pump. Turn screw clockwise to
increase pressure. Turn screw
counterclockwise to decrease
pressure. See specifications below
for correct pressure for each model.
5. Stop heater (See To Stop Heater,
page 6).
6. Remove pressure gauge. Replace
pressure gauge plug in fuel pump
port marked “GAUGE.”
