I've got a few questions about this Impco 225 propane set up I want to run on a 22R. I never saw it on the original piece of equipment it came from so I'm unsure of what connect to what.

My questions:

What do hose A and B do? just curious.
Is outlet #2 a vacuum source for other accessories the engine needs?

What should connect to #1? My guess is #3 creates a vacuum when cold and should connect to #4 the hi-idle and possibly #1 for something?

If #2 is a vacuum source it should connect to the fuel shut off valve as well as other things?

Any info on the 225 would be appreciated! Thanks
