3/4" heater hose slips right on. I extended mine to behind the entire cab. That is the size for the "blow by tube". I did nothing with the fuel drain.

Blow by extension

5/8" ID hose on the vent, so I got a 5' length of heater hose (3/4" sounds right) ... but, I bouth a " T " fitting that has the 5/8 on the base leg and one of the other legs, but 3/8 on the other. That way I have the 5/8 plugged into the crankcase vent tube, and along the frame to behind the cab, but ran a 3/8 hose forward to an area below the radiator to take in air to keep the tube clear. Not the best explanation, but it addresses the concerns of a tube extension becoming blocked and blowing a seal...
