Outer Limits 4x4 Board

Any body familiar with the sprint gas new gen lpg mixer ? I just need to know a couple of things- 1) what type of converter do i need for this and 2) there is a small hose fitting exitting the top on one side, so what goes there ? I have a couple of impco and 1 OHC converter that i hope to use 1 of.

thanks.

i have the same thing.. i dont know much about them tho..

i have only just recently started working on my engine.

Nothing is attached to the inlet on the mixer on my engine, but i am assuming that it is supposed to be vacuum operated. it lifts the plate up under vaccuum.

i can only assume that it aids in the mixing of gas and air.

my setup is this.

anyone else who has one got any tips?

Thanks for that, i am putting it on top of a 450 holley on my 3.5 rangie, but i only got it a couple of weeks ago and not sure if i need anything diiferent to what i have already - it has an impco setup at the mo.

The outlet in the pic that you are queering goes to a vacum switch, this switch lifts the plate UP when the rig is on PETROL. The vacum switch is electrially operated and recives its power from the petrol lockout.
IE: when the petrol side of the fuel is selected the petrol lockout opens and the vacum switch opens which allows vacum to lift the plate UP in the mixer and the LPG lockout valve closes. The opposite occurs when the switching is reversed to LPG fuel.

The actuall vacum comes from the vacum line that runs from the carby to the dizzy and is installed by fitting a TEE piece in that line that runs between the dizzy and a low vacum point on the carby.

p/s
Let me know if ya need pics of this vacum switch

Yep what KINGY said but make sure u put a non return valve in to.

ahhh that makes sense.

i am not running mine on gas at the moment, but i had already put a tee piece in from the carby/dizzy line.

So all you do then is put a vacuum switch in the hose running to the mixer, operated by the fuel pump/ isolation valve?

pic would be good

Thanks guys, any pics or info where to get the bits from will be appreciated.
