      September 13, 2020 at 2:27 pm Tried to be a hero by doing simple stuff myself for the first time……but it ain’t working out as planned. Changed my Racors last week. Finally found the secondary filters for the 480 CE’s and switched both out today. Forgot to add fuel into them before install. Still, STBD engine started. Stopped after a bit. Started again and pharted once or twice but then ran fine. The Port engine, well no luck. Removed the new filter, f…

Ā My 220A reguired a 36mm socket. Ā A breaker bar is handy IF your engine “room” allows it. Ā Be mindful to keep the socket seated …
