long pair of channel locks to run that 1 bolt in or small pair then try and fit a 1/4" drive ratchet with allen socket and swival might work not sure. I would loctite them we use some type of purple loctite at work with the lifts we have. ( im a forklift mechanic) Ill see it is and let you know monday works wonders never had a leak come from the fittings after using it and have the hell of a time trying to break them loose afterwords.


Those are all bolts right or look like it? Try using an regular allen and visegrips locked on the end of the allen and use it like a wrench.
