Are you sure the gas fuel rail is only 3mm diameter? Considering the gas hose is 12mm bore as far as i can make out, 3mm is a big drop. Is there not enough room to fit the gas injectors between the rocker cover and the petrol fuel rail? Alternatively there is at least one bolt i can see on the throttle body, a bracket on there would make it possible to mount them vertically.

I didn't realise about the relays, that makes more sense! I'll see about pointing it somewhere else. I did look to mount that fuel rail there but can't remember now why I went against it, perhaps it was head room but ill ave another play about today and see what I can do. Its fairly tricky to mount it somewhere close enough to keep the hose length to a minimum and even lengths.

Yea definitely 3mm internal diameter, I rang un Tinley when I ordered my extra bits and I asked about the nozzles and needing to make them bigger but he said anything more than 3mm is pointless as that the internal size so won't make a difference.
