water pressure gauge hose
 

the livorsi kits come with plastic 1/8 hose do not like that copper is also out of the ? I have seen some black (rubber) hose on some theads in the past on oso looks like a speedo hose of some sorts was a slip on with nylon zip tie . any brands or part # out there

Mine had a hard plastic hose similar to ice maker water hose. Check your local hardware store.

i used the -3 push on aeroquip( the cloth/ rubber hose.. not the stainless) . a bit expensive but better then having the thing fail inside the bulkhead... those skinny nylon lines work alright except that the ends that attach to the gage and sender are only good for a couple "attachments" . once theyve been tightend more than that they are crushed so far that you either cut the hose or it bottoms before it seals.

Mine are the black ones that they use for underground sprinklers from Lowes. Not sure of the material, but its inexpensive, and rated for a lot more pressure then I will ever need. Plus it hides better than the vaccum line does.
