Has anyone put a fuel tank underneath the back seats? I'm wanting a bigger tank but can't decide between twin tanks (how hard is this to do?) A custom tank in the centre of the boot with the spare wheel and maybe the battery being moved to the back seat.

Would a custom tank underneath the back seat be a bad idea/not worth the effort?

Thanks for any opinions and other ideas/advance for increased fuel capacity.

Cheers,

Will

<p>Hi,</p>
<p>I wouldn't put a tank on the backseat for road use and I'm not sure competition regs would allow it either?</p>
<p>Twin tanks should be relatively easy as all the parts are available just expensive.</p>

I don't think a fuel tank in the passenger cell is legal any more ?

 

I fitted a Imp fuel tank in the subframe & have a flat boot floor - it's a lot of work routing the filler pipe & vents , so on a normal car I wouldn't bother

 

also I don't think it is any bigger - but it made my project easier

 

also the spare wheel takes up more room - but a lot of cars have no spare anyway (anyone know of a modern space saver that fits a mini (12") ???

I think Sir Issigonis would have approved of the use of space with the tank in the subframe.  I wonder why he didn't do that - I suppose it means finding a new place for the battery and as you say the spare wheel takes up more room.  Still it looks very neat.

I made a space saver from an narrow 12" steel wheel that takes up very little space. Painted it black with chassis paint, got a cheap tyre and two yellow 50mph space saver stickers from Ebay. Total cost £30.

I wouldn't even bother with twin tanks unless you're in desperate need to do something for the sake of doing something. I considered it, but as you can get 300 miles out of a full tank, I want to keep the weight down!

Bigger tank? Don't think 200 ish miles for me  is bad on a single tank if im honest. Why make it complicated when it doesnt need to be.

True, I wouldn't be using it for long distance anyway, it was a bit of an after thought.

I put a second tank in - when we took the car to Monte Carlo it gave useful range - especially as petrol stations are a bit scarce on French backroads these days - also twin fuel fillers look cool! bPHxlVD.jpg
