Andrew, Do you have a picture of this "return" line location. Here is what I found on the 4412. http://www.holley.com/data/Products/Technical/199R7950-7rev3.pdf Good luck, Eddie --- " " So this Holley came up on ebay and I got it for a reasonable price (sub " $100). I know this type was fitted to the 304 and I've seen others " advertised as for 290. So, it's as cheap and quick as a rebuild for my " tired Carter 2bbl. Only the fittings aren't quite the same..... " " The worst of it seems to be that there's a fitting for a fuel return line - " Needless to say I don't have a return line - can I get away without this? carbs don't have return lines. it might be an alternate fuel inlet location. " Can I just fit a short pipe and blank it off? i'd say so - or a plug. " Tried to google and search the Holley tech stuff, but nothing there is " really helping. " " I'd happily go 4bbl but I don't have a good/cheap source for a manifold. ________________________________________________________________________ Andrew Hay the genius nature internet rambler is to see what all have seen adh@xxxxxxxxxxxxxxxxx and think what none thought ------------------------------ _______________________________________________ -------------- next part -------------- An HTML attachment was scrubbed...
