Project-Zero: Swirlpot hardline

I ordered a tube bender from Amazon, within fifteen minutes of delivery this [finely crafted] bit of 1/2" copper tube was bent up and in place.

The bend radius is just about a perfect 180˚ shot from the swirl pot outlet to the pump with barely any deformation. I might throw an Adel clamp at it for safety but it doesn't rub or touch anything. It's a pretty tidy solution.

Copper tubing is easy to get in my area, sold in 10-20ft coils in every hardware store, some stores sell it by the foot. Work hardening and cracking from excessive flex or pressure cycles won't be an issue on the low pressure side of the system.

For reference, this is what it would look like on with rubber tubing. (And on a right hand drive car, mounted on the right side of the chassis.)

ProTip: Pipe is measured from the inside diameter, tube is measured from the outside diameter.
