I have a 1998 Regal 2100 LSR I/O with a 5.0LPBYC Volvo Penta engine in it. So at the end of last year boating I noticed my steering was really heavy and I was getting a lot of resistance. So I checked the power steering fluid and it was fine. So then I checked the line going to the outboard to the inboard and noticed a bubble on my hose. My question is what is that line called and if anyone knows the part number for it. It looks like a easy fix. Sorry, new to boating.
