I did something very similar to the GOO.
I think my output to the high pressure pump was the lowest outlet so it always has fuel.
I mounted it on the same side as Jason but upside down to avoid cutting off the mounting tab.

I mentioned to Mark that I had done this and he didn't seem to think this would work. Apparently, at one time the tanks had some baffles but mine didn't and works fine this way up. It makes more sense to me to mount it the 'inlet side' of the engine.
