Its a Propane system from IMPCO. I currently have the bi-fuel setup with a IMPCO 300A mixer that goes on top of your quadrajet. The mixer is connected to a IMPCO model E evaporator type 50&70.

I have switch under the dashboard in the cabin so I can switch from gasoline to LPG and back. When I run gasoline an electrich switch blocks the supply of gasoline between the pump and the carb, so the pump never runs dry.

The only problem with this setup is that the carb is empty when running LPG. This can cause the floaters to get damaged and carbs just dont like being dry and warm all the time.

we ave more then enough places to get LPG in Europe, so I am switching to an LPG only setup with the IMPCO425 carb.

got any more questions?
