argonaut 0 Report post Posted October 20, 2019 I have a 194/204FS fitted with a Merc 4.3 MPI Need to drain off the fuel from the tank .... tried for ages with a siphon pipe - no joy, assume must be some form of anti-siphon device fitted. Is there somewhere on the engine that allows me to easily drain fuel .... using the fuel pump on the engine? I did look at removing fuel pipe to separator filter ... but it's well and truly stuck onto the brass male fitting .... and don't really want to cut it off.. Anybody know easy way to do this.?
