Please Tellie, can you tell me if it is possible to have drip leak between the composite cylinder and the base on a Clark pump. I have replaced the pipes and fittings directly below this joint and redone this many times to still get a small drip with each piston stroke with pressure. If the pressure relief valve is open there is no drip. This joint seems to be permanently sealed and obvious way to get it apart. Thanks for your time and expertise.
