More mpg (GEET)

Anybody done this? Its having petrol vapour going into the carb instead of air.It increase the mpg apparently.
There are lots of videos on youtube about it.

no carb on my fronty

No carb on any Frontera

i'm guessing, without even looking, that its some kind of unlocking hydrogen from water free energy bowlax ?

No its substituting the air filter for a bottle half filled with petrol the air is then drawn through the petrol and the resulting vapour goes into the carb air intake. Some say that the carb can be done away with altogether. There are also claim of 200mpg with this system.
Lots of vids on youtube ,I can't remember how to do links.
Of course no Fronteras have carb I should have known that,but it may be that the vapour could go into the injector pump.
I am very sceptical and lack mechanical knowledge and wondered if those on here had any thoughts.

Waste of time imho. You have an ECU that balances the air/fuel mixture on all but the 2.8 TDi which will be far more efficient. You would be better fitting a larger Fuel Pressure Regulator and let the electronic gizmo's do their thing.

If your putting half a bottle of petrol in your air box i do hope your maf sensors not plugged in the fumes will blow it up lol.
