Hi guys,
I've posted here a few times with SU carb question and I've now got one more. I'm working on a carb setup with HS4 type carbs (made by Hitachi for a Datsun) and I'm trying to figure out what to do with the fuel vapor/overflow ports. I have asked my fellow Datsun enthusiests but none of them seem to know for sure, mainly because my setup is sort of a custom fitment that they aren't too familiar with. Anyway, my fuel tank has a vapor return line that I could use but I'm not sure exactly how to hook it up. Can I just run the overflows to a catch tank and then connect the vapor return to that, or do I not need the catch tank at all? Or shoudl I put a carbon canister or filter in the overflow lines? Or something else completely different? I guess I'd really like to know what you MG guys and others do with your SU carb fuel overflows. Thanks a lot for the help - I've learned a lot here.
