A newbie here with a question. What is the purpose of the bleed/drain system on this motor and is it under pressure or vacuum? I bought a Mercury manual but it doesn't really address this and to find out about that system is why I bought the book. Also, I need to replace the hoses which uses crimp clamps. First, I don't have a crimping tool and secondly, especially on the lower 90 degree L, I couldn't get the crimper in there anyway. Is there something I can use in place of? I thought maybe zip ties but they tend to deteriorate and become brittle/break over time which would matter especially if this is pressurized vs vacuum. Thanks!
