What the ... ???

A very clever fuel baffle system, not only do these small aluminium cylinders dramatically reduce fuel surge they also help to reduce the risk of fuel explosions by preventing the formation of destructive pressures and the formation of electrostatic charges in the fuel. This system provides around-the-clock maintenance-free protection, and thanks to their small dimensions they will fit every shape of tank or container and are very simple to install, just simply pour them in! Sold per 10.5 litre.

Not seen those before, but the theory is sound.
Explosafe fuel cans are filled with an aluminium honeycomb which does the same job - stops fuel slashing about and prevents hot spots and thus explosions in the fuel can (apparently)

I'd probably give them a go if I had a fuel surge problem.

Not really any different to tank foam is it? If you want some of that Dunk, let me know

But you cant pour that in Stu.

Dont want either to be honest but just caught my eye when flicking through the demon tweeks catalogue last night.

How much room does this stuff take up in your tank?

If you poured in 10.5 ltrs of the stuff you have 10.5 ltrs less fuel in the car don't you or is that incorrect?

The way my WRX sucks fuel on a track day i'd want a totally full tank unless there were 99RON or better fuel pumps on-site. A 60ltr fuel tank in my car doesn't get me very far and reduced to 50ltrs it would be a real pain on a daily basis.

Just an observation. Please tell me to sod off if i'm talking sh1te

I think they are hollow and therefore they wont reduce the capacity of the tank by that much.

One of the drawbacks of methanol as a fuel is its corrosivity to some metals, including aluminium. Methanol, although a weak acid, attacks the oxide coating that normally protects the aluminium from corrosion:

6 CH3OH + Al2O3 → 2 Al(OCH3)3 + 3 H2O
The resulting methoxide salts are soluble in methanol, resulting in clean aluminum surface, which is readily oxidised by some dissolved oxygen. Also the methanol can act as an oxidizer:

6 CH3OH + 2 Al → 2 Al(OCH3)3 + 3 H2
This reciprocal process effectively fuels corrosion until either the metal is eaten away or the concentration of CH3OH is negligible.

Sod off, you're talking shite!

Sorry! Just couldn't resist that invitation

In english ??

I am not wanting to put it in due to the methanol corrosive action but thought it was an interesting idea.
