Received my manual after the fact of changing the filter and now having hard tie getting it to start. Did nothing else but t=change this filer. The manual says to drain all air from the fuel lines prior to changing the filter but does not say how to do this. Wondering whether or not I could have an air pocket in the line now preventing the fuel flow to the carb. The boat is a 1993 SeaRay 180 Bowrider with a mercruiser 4.3l Alpha engine serial # 0F003200, any help or ideas is appreciated.
