De-bug Filter Any Good?

I found this "De-Bug" filter the PO must have fitted in our boat.I did some googling and it has some magnets inside which supposed to kill bugs in my diesel.
I am a bit suspicious when I looked at the debug web page and see pages after pages where the company is telling me how well it works.
So my question is does it work or should I toss it? I don't really want something in line with my fuel filter that doesn't work and could cause me grief one day.

Re: De-bug Filter Any Good?

I would be highly suspicious of the effects of this device. If it is a filter, as identified, then the fuel passing through, known as the filtrate, should leave behind what is not able to pass the filter. If you do not have a collection of material that remains in the device that needs to be periodically removed; then, there is no filtration occuring! If the device is advertised as killing microbes as they are headed for the combustion within your engine, and not filtering them; I would question how the diesel engine would respond differently combusting microbes that are dead instead of alive.

Take care and joy, Aythya crew

Re: De-bug Filter Any Good?

This is the same as the Algae-X devices sold at boat shows etc. I also remember the magnetic devices that increase your fuel economy. I have 2 such devices installed in my boat and have thought of removing them since this is pure snake oil sales stuff. However they are not blocking fuel flow and to remove them would still leave me having to replace my long fuel lines or installing a connecting union (still leaves 2 joints for possible leaks) so I have procrastinated for the last six years and will probably do nothing to these devices unless they start being a problem. Sometimes doing nothing is the easiest route.

I remember a test by Practical Sailor a number of years ago reporting that they couldn't find that these units do anything. If magnetic fields of any reasonable strength could kill bacteria, all the people who were magnetic bracelets for arthritis would have their hands fall off.

Re: De-bug Filter Any Good?

The magnets won't kill or remove the bugs however they might collect any ferrous particles resulting from wear in the engine.

If you could get it through the fuel system without causing problems the engine would probably be quiet happy to burn up the bugs along with the diesel. The getting fuel with bugs to flow through the system without causing all sorts of mischief on the way is the reason we have to remove them.
