Rhys,
I've only just made my own. Very simple. Get a blank rail, drill to suit injectors, then tap the two ends for some hose barbs or similar and atach some mounts.
Google DIY fuel rail etc and you'll get the idea.
There are a few rails that are very close. magna etc and I was going to go this way, but for the sake of stuffing around, just make one.
There are plenty of places that sell DIY parts such as EFI Hardware in Mitcham.
All in cost me lest than $50.
