Is it okay to open your diesel deck fill and add fuel from a jerry can while you are under way and motoring? I refer not to the possibility of spills or getting seawater into the tank but is there any detriment to the engine?
+1. Or if you don't want to lift the jerry can out of the lazarette (for the siphon to work) just buy a simple 12V pump. I have both and always prefer the electric pump to fill fuel while motoring.Yes - use a shaker siphon and you can transfer 5 gallons in about a minute 40 seconds.
