Just a quick thanks to Andy Hornyak for calling me back before he went home at the last gasp and helping sort the ElyQ regulator plumbing out on my T-Rex 700 
Its all working fine thanks, the neighbours loved the smell of 20% Optifuel drifting past in the evening sunshine
All 30 seconds of it from the VERY quick test hover
