Email this Video to a FriendClean fuel is THE essential ingredient when it comes to a smooth running diesel engine. Understanding the path that the diesel fuel flows in (and what it flows through) — all the way from the tank to injectors — is necessary information for any skipper of a diesel powered boat.

Again this is a great series of videos – I feel as if I know ten times more abut diesel engines than I did before – so thanks very much. I would like to know a little more about the fuel injectors. You show a Direct and Indirect injector component. Do you have a preference as to which type is the better in terms of efficiency or reliability? Also – you mention that one can ‘swap injectors” in order to do a diagnostic test but the injector lines look like they’re made specifically for one cylinder position only. So just how does one switch the injectors around if those lines are as solid and specialized as they look?
Thanks

Great instruction!
The same applies to gasoline powered engines. Always check the bottom of your fuel tank for water and dirt using a copper sounding tube and a small PAR pump and pump several quarts of fuel into a container to make certain that the fuel is clean.
You’d be amazed and appalled at what you may find lurking there.

Thank goodness for oil soak pads!! They also make good knee pads in a pinch. JCB

Could you make a video showing how to make a diesel fuel polishing system using a fuel/water separator and fuel filter, or if you know of a better way than do that one of course.
I have seen one that was mounted on a sheet of 16×20 plywood, It could be stored on board to be used when the source of the fuel was not known. Thank you so much for making this diesel video and all of the others too. Mike Carter.

Hey-
Nice job on the tutorial. Good camera, lighting and informative scripts. Kudos to your video team, or guy. FYI- I do video production down here in Sag Harbor, NY. and sail my 1970 Dufour Arpege around the Northeastern coastline.
Thanks-

Nice video, and nice point about the clogged lift-pump filter.
Boy, does this show why you don’t want to have to service THAT engine, though — the designer decided that making filter-changes clean and easy wasn’t important enough to slightly re-route the coolant hose, or slightly offset the filter location. It could be worse — could the the horrid old Westerbeke 4-107 with its horizontally mounted oil filter located low on the engine. But even on the 4-107, I can change the secondary filter more easily and cleanly than on this thing.
