Making a New Pump Tube

A Burmos 96 stove was sent to me for removal of a badly stuck NRV. After replacement of the NRV there was still leaking going on in the pump tube. I removed the pump while the stove was pressured and added some water in the pump tube. Using a small but strong flashlight, it could be seen there were several locations emitting streams of bubbles around the inside of the pump tube. This was likely caused by poorly drawn brass tubing that left stresses in the tubing back when the stove was made.

The pump tube was pulled and the tube was replaced with one I manufactured to match here in the BD Labs. Those photos follow.
