fuel pressure regulator?

[caddylover]

any idea where this is located on my 2012 Pro R 800? is it on the fuel pump or is it on the fuel rail? i will randomly hit a wall and sled loses power at around 6800-7500 if i floor it. i can feather through it at times, but most times i just have to let off throttle and work my way through it. Reeds are good. Might be fuel pump, but it only happens in that rpm range or if i hammer it from 5000 rpm up to 8200rpm. Maybe microdampners? I'm at a loss and have been chasing this for years now
