can anyone help with VP on gas heater hose setup

[fishman]

charliekoellner@hotmail.comyeah g'day, i have a VN series 2 exec wagon running a VP motor on gas
my problem is that the previous owner had a interior heater leak so had the heater hoses that come outta the firewall disconnected and just run hoses from block to gas mixer so no heater or demister.what i want to know is there someone on this site who either has VP on gas who can draw diagram of correct setup of hoses or perhaps some photos of their setup i have done a cut and shut of heater radiator and just wanna get the engine side sorted
