I have a few harbor freight hose reels. The reels there self are good. It’s the hoses on them that are junk. I just want replace the hoses on the reels. What are good hoses to use for this? 

I just found something on that. What I read was to slice into the - side of the coil. Run wires to a toggle switch.  At will crank put won’t start because it’s not firing. Any suggestions on what kind of toggle switch would be best for this?
