I have a Lovato diesel gas system on my 4.2 diesel patrol. Gas consumption has dropped from 3.5L / 100km to 1.6litres / 100kms with the difference being now made up with increased diesel consumption. I have changed the gas particle filter with no change. The system does have a ECU. Engine speed information comes from the alternator.

.


Two hoses leave the gas filter housing. One goes via a solenoid shut off valve to a fitting on the aircleaner hose injecting the gas. There is not jet here it is simply piped into the intake. The other hose goes down to some sort of device on the exhaust which I assume provides vacuumn.I have attached some pictures.


Any suggestions as to what could be going wrong would be appreciated.
