SUMidel in Sydney carry a big range of spares for British SU's - http://www.sumidel.com/
As far as hoses go, all you need is 3 per carb - one from fuel pump / fuel rail into the top of float chamber, small one to get fuel from the bottom of the float chamber to the jet on the base of the carb, and one to drain any overflow from the float chamber.
Thanks Dave. I will have a look again. Its runs fine, not as responsive as i would like but thought the carbs just need a tune.
Those are British SU's not Hitachi SU's and they look a little undersize based on the surface of the intake manifold and how the carbs mate up to them. I'd measure the throats to get an idea of their size.
Hard to advise on what's missing since they are off another market car. Usually it's HS6 SU's that get fitted to L-series (L24-L28's). However my experience with HS6;s is that they were not nearly as good quality as the Hitachi made SUs.
As suggested contact the website above for help with your particular model of carb.
Thanka Gav. Will have measure and go from them. I am hoping they are not undersized, didnt want to change anything just yet. Haha
Hey mate, I have a spare cable clamp that I would be happy to part with.
As for air cleaners I had a pair of "Ramflow" Filters on my British SU H6's which had a great induction noise and seemed to perform fairly well.
This shows how they mounted and what they look like. It would probably be possible to make something custom or re-drill your stock airbox.
Hey Andrew, that'd be great. I have a feeling you might be near me too. I will pm you.
I went through some of my parts before and it seems this came with Ramflos but dont go on the mounting plate well anymore. Did u get yours locally? I assume i would need and airbox for roadworthy though.
