CAUTION:
The pump inlet must not be pressurised at any time. This will cause fuel to flow from
the air eliminator. Unregulated connection to an above ground tank will cause pressurisation.
CAUTION:
For above ground tanks a regulator valve such as a Tokheim valve or similar device
MUST be used so that the inlet of the pump cannot become pressurised at any time.
NOTE:
The air switch is not to be disconnected. Disconnection will void NSC and TMU approvals.
NOTE:
The air eliminator chamber is not to be piped back to the tank. This will prevent it from
working and may damage the pump.
