Ken, the coolant tank on my 95 Bounder failed several years ago. I'm using a small tank from the parts store with no problem.
The first place to look for leaks on your F53 is the left lower corner of the radiator. The brass tabs on the radiator lose tension and let the gasket leak. If you see coolant dripping from the center hole in the core support, it's the radiator.
The Factory OEM jacks were 3 point Power Gear. If you have 4 point jacks, they are aftermarket and probably HWH. Don't worry about getting the hose too long, just lose the extra length in a loop.
