I am going to be running the zex dry 100 shot kit on stock motor I am looking for fuel pressure cutoff switches and dont know which psi to get. I know 7psi or so if for carbs so would I need an adjustable 25-50 psi switch?

right, you need the hi pressure switch. set it just a bit below your systems pressure

adding a walbro 255 fuel pump and new filter might be a good idea
since the point is to maintain pressure
