Fuel Lines - copper / hose location (Pre Cat)

[Tegriffic]

So I'm replacing the fuel hoses and have reached the engine end. I was expecting to hoses to and from the fuel rail to meet the copper line down by the bell housing - per older postings on PH. Mine doesn't - the copper lines appear to run vertically up to about rocker cover level. Obviously this makes it easier as I can get pretty good access but I'm wondering why it's not at the bell housing about 10 inches down as I understand it normal. The car is a 1992 Precat - did the pre cats have the join here rather than lower down or does it like I have a non standard layout here ?

Thanks.
