  • Page 32: Notes For Use And Maintenance Of Fuel Pumps

    NOTES FOR USE AND MAINTENANCE OF FUEL PUMPS Make sure that the by-pass plug is not used in a single pipe installation, because the fuel unit will not function properly and damage to the pump and burner motor could result. Do not use fuel with additives to avoid the possible forma- tion over time of compounds which may deposit between the gear teeth, thus obstructing them.
