EFI return line, use emissions return?

Well, since I have a buddy with a really nice TIG welder, I'll porbably go for welding a pipe through the sender unit flange, allso saves me routing any pressurized line in to the boot.

But If I didnæt have the option of welding stuff.. hmm.. no telling what I'd get up to! :)

As my return line will be about the same diameter as the supply line, I hope I'll be okay.

Friend of mine got him self a custom alu tank welded up with baffles and all other niceties imaginable.. But then again, hes building a 1978 Opel Kadet with a 400+ HP turbo engine going in. As opposed to me he'll NEED baffling! :)
