looks more like it is collapsed. i do not see a good way to fix it. it is just brazed into the resevoir can. it can be replaced. new cans are available also.
+1 It would be tough to keep from showing evidence of the repair.
What I have done on similar "NON Concours" jobs will straighten the line to "usable" and depending on how bad it is bent, might work out good enough, possibly perfect.
Using a torch (Benzo-matic might do it too) you can heat the sides of that flattened out tubing mildly while pushing the bent tubing towards being straightened and squeezing in on the sides of the flattened area. Problem being you might "square" out the tubing so the effort ought to be more in the heat and tweek using litle effort on the "squeeze".Let the HEAT do the majority of the work a bit more that the tweek. If you get a right balance of all three, heat, tweek and squeeze, you might just get it perfect but you really have only one shot.
You will need both hands if not two sets of hands for this task. It might help to have a 2nd set of hands that understand what you are trying to do AND maybe secure the pump or the reservoir, say with the nipple facing upwards with the pump shaft facing away from you to a vice or maybe strap it to a table...think of what will hold the pump down without any effort so it will not move around. I've use a steel insert like a steel dowel the size of the hole in the tubing (1/4 inch extension bar? Maybe that works on 3/8" tubing?) I have been successful at straightening tubing bent this much before and at the same time, I have also been successful to the extent that the tubing"squared out" making it fuctional anyways.
Good luck whatever way you go, but I would certainly try at least to straighten it first.
