Oh don't worry guys, I'm not going to use rubber hose for the whole line!
I am going to use Poly Armor metal line and rubber fuel line hose for the connecting sections (copying what was there before) with hose clamps.
I finally found THIS which is what I had been looking for:

*Wreckedchevy: thanks for the one you found me, it does look compact, but I'm a bit fearful of plactic myself. The water valve is set up for PEX and although I love PEX for plumbing, I might ought to use one made for rubber hose.
*Now that boat one I might could fix up so it could actually mount to the tank with a magnent or velcro or something......volksworld is on to something there.
