Day tank
pump prImIng
proCeDure
e Day Tank pump is shipped from the factory
pre-primed with SAE 30 oil. On initial start-up the
pump must be manually pre-primed. Do not prime
the system by running the pump motor! Normally
it is not necessary to ll the supply line with fuel to
prime the pump.
1. Remove the steel plug from the pump priming tee,
insert a short piece of pipe in the pump priming
tee and attach a reducing coupler or funnel.
2. Fill the line from the check valve to the pump with
fuel oil or lube oil. Energize the pump/motor and
observe fuel owing through the clear ex hose.
Allow the pipe to drain about halfway, then hold
your hand on the top of the pipe to temporarily
seal the open tee. e oil drawn into the pump
will act to seal the pump and allow a large vacuum
to be generated. Repeat as required until line is
primed. Aer pump is primed remove pipe/funnel
and replace plug in pump priming tee.
This is an industrial prod-
uct, not a consumer prod-
uct. It must be specied,
installed, operated and
maintained by individuals
equipped with the appro-
priate training and skills.
Attempting to pre-prime
the Day Tank delivery
system by running the
pump will cause serious
damage to the pump!
