When sizing SPMB units, remember that the pressures indi-
cated are at the pump outlet.
All pumps relying on atmospheric pressure to push the fuel oil
into them are subject to cavitation. As fuel viscosity (thick-
ness) increases, the tendency for cavitation becomes greater.
Therefore, iti is best to mount the pump at the base of the
tank and to use the largest diameter, shortest length, and
straightest inlet possible.
A large diameter inlet pipe or hose necked-down at the pump
is preferable to a longer lentth of similar diameter pipe be-
cause the fuel tends to adhere to the inside of the pipe.
When initially starting a unit, it is desireable and sometimes
necessary to have a vent valve or plug on the pressure side
of the pump to facilitate its priming.
