z
Pipes should not contain air pockets. Rapid attachment joint should therefore be avoided and threaded or mechanical seal junc-
tions preferred. Junction threads, elbow joints and couplings should be sealed with removable sg component. The number of junc-
tions should be kept to a minimum as they are a possible source of leakage.
z
Do not use PTFE tape on the suction and return line pipes to avoid the possibility that particles enter circulation. These could depo-
sit on the pump filter or the nozzle, reducing efficiency. Always use O-Rings or mechanical seal (copper or aluminium gaskets) jun-
ctions if possible.
z
An external filter should always be installed in the suction line upstream of the fuel unit.
