You will want to buy a Snapon Hose hook for this. They get stuck on the fittings that you don't have enough room to find any leverage... and slicing through a hose on a plastic barb isn't the best solution. Hose hook breaks it loose! (One of the few times to be glad someone used crappy vinyl, with no wire...)
A set of nut drivers... and a ratcheting screw driver are very nice things to have. Flex joints with electrical
tape, or the spring type extensions are also good tools... if they used hose clamps with a hex head.
When it all goes back together, pay attention to where the screw head ends up facing... when its tight. Seems like folks set it where they want it to be, and crank it down only to have the last turn put it in a position that requires a contortionist to get off! Sometimes a cut off wheel
on a dremel is worth while.
(The last one I did was a full electric raritan
, installed with a hose so short it wouldn't lift
off both the mounting studs. That sucked.)
