Cheers for that Harley,

Now it all becomes clearer! I completely missed the fact that the Mig tank fits under the inlets. I have just tried the install as you explained and I can see it will work fine. You also cleared up another question that I had, where do I put the smoke pump mechanism? Well now I know I can put it on the floor as per your instructions. I now thinking about how I would secure the fuel header tank between the inlets as it is above the smoke pump. I am thinking of either a small former screwed to the inlets and then the tank fastened to this or alternatively simply velcroing the tank to the inlets. What did you do?

Any pictures would be gratefully received.

Thanks again.

Geoff.
