Steering box Inlet hose

Perhaps a silly question, but I seem to be stuck on this....replacing the Steering box inlet hose that runs down from the hydroboost. How on God's green earth does one access the fitting on the top of the steering box? Based on the replacement hose, the fitting is an 18mm. But I can't get a wrench, crowfoot or anything in there to save my life. Tried from below, from top, from the LF wheel well. My last option is to remove the fan shroud and try that route. Any thoughts would be appreciated!

I removed the tire fender well and the boost tube

Always use a "flare-nut" wrench for these sort of fittings. A traditional open-end wrench could damage the nut. Jim
