I have the 150 gph model on my truck but I'm pretty sure it was supposed to be the 95 gph model when I ordered it, didn't realize it was the bigger one till the replacement filters I ordered were too small.  The 95 gph model will be plenty big for your sprayer, I know guys running 1,200+ flywheel hp in trucks on the 150 model and I can't pull the one in my truck down below 21 psi at 265hp.  The only issue I've ever had with mine was the filters gelled on my once the first year, I had filled with blended fuel the night before but didn't let it run long enough to mix after fueling up but gelling shouldn't ever be an issue with a sprayer.
