PUMP PRESSURE ADJUSTMENT FOR HEATERS WITH FUEL FILTER INTERNAL TO PUMP

1.Remove pressure gauge plug from fuel pump port marked “GAUGE.”

2.Install accessory pressure gauge (part number 130-24132) to fuel pump port marked “GAUGE” (see Figure 12). Do not use bleeder valve port to check the pressure. The bleeder valve port contains pressure higher than operating pressure. Setting pump pressure with gauge in the bleeder valve port results in wrong operating pressure.

3.Start heater (see Operation, page 4).Allow motor to reach full speed.
