Default alky injection nozzle, point up or down?

should nozzle be pointing up inside of IC pipe ( spraying alky upward) or pointing down?

i've heard that you should install pointing up because of some presure might suck out alky from nozzle or whatever. is this true? does it matter at all

Most setups that I have seen have the nozzle facing up...

It doesn't matter. The only reason I put mine in pointing up is it hides the nozzles and hose.
Most WI systems use a check valve to stop boost from "blowing" the lines empty.
