Ok, I know you aren't supposed to do it, but who has, and who has had problems afterwards? ALH lines are plentiful, AHUs are not, which is what I need. While I can see tight bends causing problems, I really don't see how a gentle bend could do anything.
i would imagine there to be a 'coating' if waste veg was used constantly and then no purge :lol:. i would heat the metal before bending though...
as long as the injector lines retain the same length you should be fine.
