what...glue?!  
nope don't do that, use a pair of steel straps, with thin rubber or foam between them and the tank.

MK say they just use sikaflex now and don't bother with the straps anymore.
I'd personally prefer straps in case I ever have to take the thing out at some point.

or really really long and wide cable ties?
longest I've found, in stainless are 1 m but you can double/triple/... then up.
why aren't tanks made with tabs so that they can be bolted to chassis?

Best thing about the straps compared to bolt on tabs is in a crash the tank can move around a bit without tearing, where as a tab may rip off and
cause the tank to leak. Most production cars with tabs have deformable mountings (simple brackets) that will give and bend without stressing the tank
too much.

Bah, beaten to the post by the Whippy.
Tabs on an aluminium tank can crack at the weld as they all move slightly under cornering due to the weight transfer as the fuel sloshes round.
Are SVA ok with glued in tanks? Guess they must be, but seems a bit on the edge.

i wasn't to confident just using Sikaflex only as MK suggested so added a strap as well.
Always nearly finished.

WOW really??? Very very surprised to hear that.
If it looks wrong it probably is wrong.
