Water connectors on SU manifolds
Posted 20 July 2015 - 08:36 PM
my ones are totally gone. it looks like one of those "british pipe thread" fittings and some sort of a copper washer (guessing only)
looks like brass body and a steel nipple on it

Following this thread, hoping some more information comes to surface in respect to replacing the entire water connector/pipe setup.

he also has the rubber hose that goes from the thermostat

Mine started rotting out many many years ago & I simply disconnected it all & removed the remnants after nearly getting stranded when one of the small rubber hoses blew. I just used a threaded plug on the thermostat housing. That was with the original flat-tops. Later on I installed round-tops. With both types of carbs the car ran fine without all that water pre-heat system or whatever the hell it's for.
I need a whole new water connector setup for my N36 manifold - pipes and all.
But if you want to or have to rebuild the water reticulation system then I would have thought generic brass or steel nipples would be available in the right sizes from Supercheap or somesuch - maybe hanging on one of those small-parts & bolts display mobiles you see in there??? Or look online. And I'd replace the central metal pipe between the two manifolds (which corrodes & blocks with scale anyway) with a rubber pipe as with the rest.

does anyone know the size? i've tried a couple of brass fittings at bunings and that didn't work

A bit odd for a water fitting into aluminium but that's what it is....doubt that you'd get a fitting unless it came from a hydraulic supplier and its doubtful . Item 16 is a rubber seal of some sort ...mine was badly damaged and maybe not even original. The tube is 10mm outside diameter.

To me, for a hobby car only driven sporadically, fuel economy hardly seems worth considering.
And all the extra pipes/hoses/connections are more things to leak or burst or go wrong, as I've already experienced.
Is there any 'road worthy' requirement in Australia to retain them as a factory fitment?
There are suppliers of such fittings on-line, if you can correctly size/ID what you need you could well be in luck.
And not Bunnings, maybe try a Supercheap or Repco small auto parts stand for brass fittings like I suggested earlier. Or go to an industrial hose couplings supplier - Yellow Pages - they will have them, & adaptors if needed too.

all fine and dandy, except that the fitting is mild steel, totally uncoated, so that
he said he had a stainless version that he could order ( at $30), so i'll keep on looking for a brass version
supercheap/repco didn't have anything ...
