Abstract
A submersible turbine pump (STP) is provided. The STP includes a manifold having an integral siphon connection coupled to a fuel flow path in the STP and a siphon cartridge removably inserted into the manifold via the siphon connection. In general, the siphon cartridge includes a nozzle that directs fuel from the fuel flow path through a venturi when the STP is energized, thereby creating a vacuum in a chamber within the siphon cartridge. A connection point of the siphon cartridge is fluidly coupled to the chamber such that a fluid connection is provided from the exterior of the siphon cartridge to the vacuum.
