A submersible turbine pump (STP) comprising a manifold, a yoke assembly including a yoke sleeve integrally connected to the manifold, and a packer removably secured to the manifold is provided. The manifold includes an electrical cavity that receives electrical wiring from an external source. The yoke sleeve has a hollow interior and is integrally connected to manifold, and a first end of the yoke sleeve is within the electrical cavity. The packer includes a chamber having a yoke sleeve inlet port and an electrical conduit inlet port. The yoke sleeve inlet port receives a second end of the yoke sleeve extending from the manifold, and the electrical conduit inlet port receives an electrical conduit extending from a pump within an underground storage tank. The electrical wiring passes from the electrical cavity to the chamber through the yoke sleeve and then to the pump through the electrical conduit.
