As the pictures below depict: The existing plastic engine seawater coolant anti syphon loop T connection was removed and discovered that not only was the bottom plastic hose barb broken, the top plastic hose barb was also broken. Also discovered that the outlet hose barb that is suppose to route water to the stuffing box to lubricate the packing gland was completely blocked with what appeared to be rusted metal flakes and other unknown material - whatever it was, it was concrete-like-hard and was not able to be removed. Might explain why the stuffing box packing glands were found to be burnt black and glass-like hard.
The new bronze anti syphon loop T connection is shown with the original broken plastic anti syphon loop T connection for comparison. The new components and hoses were installed as depicted in the above diagram. Additional holes were cut in the wood floor to accommodate the new hoses and not violate the hose bend radius. A steel rubber cushioned clamp was placed around the bronze pipe nipple on the new T connection and secured with a screw to the side wall. The 1/2-inch outlet hose was connected to the stuffing box hose barb and secured with two clamps.
