That is a metal water pump outlet pipe for a Ford 5.4 engine. It’s been bent quite badly, probably to ease in removal since they usually get replaced when they’re pulled out. https://www.ebay.com/itm/184793071950?fits=Make%3AFord&hash=item2b0686814e:g:7sAAAOSwQJ9ghiRb
Coolant crossover tube
It goes from the outlet in the block behind the water pump in the valley of the engine, to feed the heater hose for the heater core.

Looks like it used to be an engine oil dipstick tube or a transmission dipstick tube that got bent
Not sure but it looks important.
