Couple of fuel tank questions...

[jasongray5]

Bloke thats ment to be making it has let me down abit, so, was thinking i could do it myself!
Are there any issues with using steel instead of ally?

And Is there a problem with sitting it ontop of the diff cage instead of behind it?

Is there any problem with my tank being wide, deep, but not very tall (570x350x140) it will have a 100x100x100 swirl pot on the bottom. With at least 4 baffles in it to stop the slosh from beeing so shallow?

Cheers Guys, Jas
