fuel line magnets fact or crap

Featured Replies

hi my mates been selling these for years ive always kept clear but it appears they do work anyone tried them on here the kit he does is 1 for each injector and one fuel line

glad for some feedback

I have 10 on each injector - 50+mpg.

They are a waste of time and fools gold.

as i thought he does this lighter test seen it 100 times but always stood my ground

Your mate is a thief and a con man.

A what test?

They're not just fools gold, they can damage your fuel lines.

Not through magnet force, but just by the act of attaching a lump of heavy metal, which swings around, clonks into things, rubs the fuel line, etc.

he gets a oven lighter and puts a magnet around the base then tells you to feel how the flame feels stronger

How can magnets help fuel? The only benefit I can imagine is for catching metal in the lines so it can cause damage.

funny he has just got another car and hasnt fitted them lol

Out of interest, what magnets does he use?

this is the funny thing he spent a good year or so finding them and testing it it all seems good but im still thinking suger pills for belly ache

Oh no! 5 dollar a gal! that's a buck 10 a litre! George bush you robbing ******!

In theory, this does apparently work- NASA did some tests on it.

However, for it to properly work you'd need an entire head made out of a magnet. Not really very practical. :giggle:

EDIT: here's the NASA stuff. With Xenon fuel.

How does this prove that the magnets on the fuel line will improve MPG ect?

I am genuinely perplexed, surely this has to be snake oil in the highest form as car manufacturers would have already jumped on this big time and had some sort of magnetic fuel line system.

Plus, do regular magnets not loose their ability to magnetism when they are heated - IE sitting in an engine bay for however long!

Thoughts......

That's what I said- the tiny magnet at the top of the fuel line would do nothing for it. Needs to be a large surface area, i.e. the head being a magnet.

Not that sort of heat, definitely not. They do have a finite life though, and shock can reduce magnetism dramatically.

Shock..? The they would def get a beating!

Either way, no magnets will be going into my engine bay!

Don't blame you. Any unshielded magnets close to the injectors is going to be bad news as well. (Solenoids...)

I know of a large haulage company that did a 12 month trial with magnets fitted to several off the vehicles they ran @ 44te fitted with cummins M10 and M11 engines, with a view to increasing the fuel efficiency of its fleet.

They used positive and negetive magnets fitted to the inlet manifold and fuel lines, I cant remember which way round they were fitted ie negetive on the manifold and positive on the fuel lines or the other way round, but the idea was that the charged inlet air and injected fuel would be attracted to each other inside the cylinders.

This was supposed to give improved combustion and increase the engines fuel efficiency.

However after the 12 months had passed and an annual mileage of approx 150K to 200K for each vehicle on trail, they recorded no improvement in mpg compared to similar vehicles in the fleet that were not fitted with magnets and monitored over the same time peroid.

No supprise there then lol.

Also, I remember cummins engine company being very concerned/worried about what side effects placing magnets on the fuel lines would have on the engine ECU and engine wiring harness which were located on the N/S of the engine next to the fuel pump and any warranty implications.

I'm not surprised. With the amount of sensors and solenoids all over modern engines like the VERY high fuel pressure Cummins QSB I would think it a very bad idea.
