V8 astronomical fuel usage

Budgie:
Yes the flame trap does just unscrew, standard righthand thread. If it's not coming then try when the engine is warm.  
There is an o-ring under it to form a seal so WD40 won't help.  :wink:

If you can't find a problem and altering the timing doesn't do anything then a trip to an LPG specialist could be the way to go, if only to make sure both the LPG & petrol sides are both set correctly.

Range Rover Blues:
If you check the resistance of the injectors at the ECU multi plug that shgould tell you how many injectors are connected to each bank.  How did the installer fit the injector cut-out? is it emulators? or a cut out relay in the injector power supply?

What colour are your spark plugs?

Have you checked for a fuel leak?
