Hello. new owner of 1999 Regal commodore and new to boating. I have a few problems that I hope someone can help me with. 1. water seems to gather in the area around the shower pump. I have checked the hoses and the casing and they look fine. The water seems to come in through a one inch pipe from the stern direction. where does this pipe go? 2. Whilst running fuel gauge seems to be jammed on half tank no matter how much fuel is on board. When ignition off gauge reads zero.
