AHA, u have no AC, that's why u get 18mpg...
then u have a stepper motor instead of the screw valve to calibrate the flow.
The reducer looks like a LANDI RENZO (good one) or a copy of it.
U have a high pressure leak on the upper water hose, see that brown rust and the green oxidation on the brass screws?
It's probably the o-ring under the 90° plastic junction.
Funny, u have the reducer in the same place where i have it, there's not much space in the bay.. did they make a spiral on the copper tube between the reducer and the safety valve?
Hope that bracket is not bolted on the shock absorber...

That's a sequential phased multipoint lpg injectors, actually not used any more, now we have separated injectors with shorter hoses, cause of the feedback pressure differences.

AAAHHH!!! those long tubes... they had just to rotate the multi-valve and mount it upsidedown, and the metal frame, will rust...
Looks like a tomasetto, or is it landi too?

mine was done when i got it so i would be lying if i told you that i know a good supplier im in the uk there are a lot of fitters here due to the hi cost of petrolium and my local garage services my lpg system as i see that to be safe rather than me messing with it but sure you can find plenty on the net to read about it
