aircobra Posted July 20, 2015 Share Posted July 20, 2015 #15 and #16 on this diagram https://www.zcardepot.com/index.php?route=product/product&product_id=474&search=200-518 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 any ideas?

theremm Posted July 20, 2015 Share Posted July 20, 2015 I need a whole new water connector setup for my N36 manifold - pipes and all. Following this thread, hoping some more information comes to surface in respect to replacing the entire water connector/pipe setup. Quote Link to comment Share on other sites More sharing options...
aircobra Posted July 20, 2015 Author Share Posted July 20, 2015 the zcarsource guys has the ones that go into the thermostat and the outer connect points - that's the link i posted he also has the rubber hose that goes from the thermostat Quote Link to comment Share on other sites More sharing options...
gilltech Posted July 20, 2015 Share Posted July 20, 2015 I need a whole new water connector setup for my N36 manifold - pipes and all. 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. 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.

theremm Posted July 20, 2015 Share Posted July 20, 2015 Mmm might try removing them all together planning to use the N36 with roundtops on a 240z Quote Link to comment Share on other sites More sharing options...
aircobra Posted July 20, 2015 Author Share Posted July 20, 2015 my one already had a rubber hose in between. does anyone know the size? i've tried a couple of brass fittings at bunings and that didn't work Quote Link to comment Share on other sites More sharing options...
PeterH Posted July 20, 2015 Share Posted July 20, 2015 I have a spare set of carbies on E88m manifolds dismantled at the moment.... the nut, item 15, in the link has a metric fine thread M16 X 1.5. 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. Quote Link to comment Share on other sites More sharing options...
PeterH Posted July 20, 2015 Share Posted July 20, 2015 The seals item 16 are listed in the parts book as (14013-73400 ring - rubber water tube) I'm sure a thick section o ring would do the job. Quote Link to comment Share on other sites More sharing options...
gilltech Posted July 21, 2015 Share Posted July 21, 2015 I presume the purpose of the water circulation is to bring the air/fuel mix to a warmer temperature more quickly & so shorten the period of rich mixture / choke needed thereby saving fuel, is that it in a nutshell? 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. Quote Link to comment Share on other sites More sharing options...
aircobra Posted August 1, 2015 Author Share Posted August 1, 2015 ok, went to enzed and they had a M10x1.5 adapter, which then took a brass nipple insert 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 ...
