An apparatus and method for directionally disposing an elongated flexible member in a pressurized conduit. The method includes inserting a bent end portion of an elongated hollow body through an opening in fluid communication with a well valve and defined by a pressurized conduit, the bent end portion being disposed in a pre-determined direction and location within the pressurized conduit; inserting a lead portion of an elongated flexible member into a fluid passageway defined by a primary valve, the fluid passageway of the primary valve being in sealed fluid relationship with the elongated hollow body which, in turn, is in sealed fluid relationship with the pressurized conduit, so that the lead portion of the elongated flexible member is inserted through the bend end portion and into the pressurized conduit by a pre-determined distance; and thereafter retaining in place the inserted elongated flexible member, whereby the elongated flexible member is directionally disposed in the pressurized conduit.
