Any one using Dual port chemical injector Hi Draw with any luck?

That was what I was hoping to hear. My new trailer is going to have a 5.5 @ 2500 for house washing and a 8 @3500 for surface cleaning but I’d like to be able to house wash with the 8 as well. So being able to use the same size injectors on both machines is a plus. Will I still be able to dilute my SH when run through the 8 with the 3-5 injector? My mix is 2 gals of SH for every 5 gals of mix.
