max fuel pressure?
 

I should be getting my raptor 150 today soon and I wasn't sure how high to set the fuel pressure. I think I remember reading 18psi is the most you want with a stock vp. Just want to know what to set it at when I put it on for best results.

don't go over 20 is what I hear. I run mine at 20 now and it's very happy. if you can maintain 18 thats perfect. for some reason my pump couldn't handle 15psi constant so we changed spring and it doesn't move off 20.
