what are the issues with running the tanks in the boot?
mot fail?

In Australia sedans are alright but hatches are not due to the boot being open to the cabin. Don't know if it helps but that's what I would enquire about.

If it's an MOT fail, make a quick-release valve in between the 2 tanks so that it's easily removable for MOT.

Doesn't that kind of defeat the object? I presume he wants one in the boot so he can get rid of the original one under the boot.

Fuel cells should be fine for an MOT, just make sure you use non-permeable fuel hoses to prevent fumes in the car.

For motorsport use a fully sealed fire wall is required between the tank and cockpit. From memory fuel lines may run through the cockpit for motorsport use but must be a continuous length of hose in the cockpit.

cheers for the info guys, thinking about it im at no advantage by moving the tank.
where it is is probs best as it keeps the cars low centre of gravity if anything!
