Magnetic Fuel Conditioner

When we got the coach over 5 years ago, it had one of these Magnetic Fuel Conditioners cleaners on it:

LG-X Series Fuel Conditioners - Diesel Fuels

We've never had any type of fuel issue (knock on wood) but was just wondering if anyone had any experience with them, do they really do anything, or are they "snake oil" ?

The only thing I've ever heard of along those lines was a devise Pittsburg Power came out with in the 90's that removes air bubbles from the fuel being supplied from the injector pump. I may and probably am off subject but would like to hear more of the claims made by the magnet gizmo.

We've had our coach for about 11 years, and while it does not enjoy the "benefits" of a Magnetic Fuel Conditioner, we also can say we have never had any fuel problems (other than paying for it...).  Between road trips, our coach sits for long periods of time in our driveway, totally exposed to harsh and varied environmental conditions.  The fuel in our tank has certainly had ample opportunity to get "stale" and suffer the decomposition described in the "Theory of Operation" document linked below.  And yet, so far, we've had zero problems starting and running our engine even after our coach has been sitting motionless for months. 

In my opinion, based on 60+ years of tinkering with engines, logical reasoning, and a highly developed BS detector, I would place this device in the "Snake Oil" category.  TIFWIW

Thinking about this device reminded me that back in the day (the 60's) there used to be magnetic "fuel conditioners" sold in the back pages of hotrod mags.  You were suppose to attach the magnets to the fuel line going from the gas tank to the carb.  They were absolutely guaranteed to increase power and mileage, or your money back.  Right.

Seems the same scam is still going strong, except now the target is home oil-fired heating boilers and they claim the technology is based on NASA Magnet Fuel Science.  WOW!  Rocket science!

 Sounds a lot like JC Whitney's rebuild pellets  Just drop them in the engine oil and rebuild the engine while you drive  They were on the back pages of the catalog also

A strong magnet in the bottom of a rusty tank might collect some rust and keep it from entering the line.

The air removal makes sense. More filter too.
