If you are trying to remove the booster line in preparation to remove the IM, the easiest way is to seperate it at the 'T' mentioned in the referenced post above and then after providing clearance (it's somewhat flexible), remove the IM with that segment of the boost line intact and still in place. That 'T' is on the driver's side of the engine and easily tracked from the back of the IM.
Then you have the view shown in the OP's picture and can remove and replace the line when you're ready to re-install.
