79 m20j removal of fuel line from throttle body ("injector")

[I have this friend..]

This hose is a ms28741-4-0150

And it has fire sleeve crimped in place access is very tight.

Can i remove this with a 9/16in open end crows foot and extension?

Should i try to get 1/4in drive for smaller tool?

(Its a 2 hour drive each way to airplane want to be prepared)

You can infact do this with a 2ft extension 3/8" drive and a 9/16" crowesfoot. 

Grind down the crowsfoot with a dremel to make it as skinny as possible

You can actually access it from both the right and left side of engine which is useful because you can only move it one flat a time.

Note, this is with a open-end crows foot not a modified box-end crows foot.
