does anyone know where I can get all 3 manifold water lines new for my 78 280z?

She's sprung another leak!

The rubber ones? I just cut them from bulk hose.

the rubber ones, wasn't the bulk hose too big?

I used 5/16" i.d. EFI fuel line. Kind of overkill but I only had to change them once.

good idea, was there a trick you used to replace the molded 90? I've been fighting with it for a while with no luck.

I got it on and the it's bent there wont be much water going through it. not sure what plan b is yet.

No trick, it was a pain to change that one as I recall but the hose I used was stiff enough to make the 90 w/o collapsing.

Go to Autozone or wherever and ask to let you look at all their molded hoses. Usually you can find a hose for another application that is close enough to work. I recently did this for the hose that runs from the intake to the thermostat housing on my '72. Kind of a bent S shape and I found one that worked perfectly after trimming.
