Ive tried searching, I know a bunch of people have done this, I just need to know what size hose it is thatll slip over it. Do they sell the hose in the shape of a u at like discount auto? Thanks guys.

Oh and when i take the hoses off, what do i do with them? What are they connected to? do i need to plug them? pull them off? etc.
 
The heater hoses are 5/8" & 3/4". You can get a stepped hose fitting from Home Depot to join the two different size hoses together.
