He doesn't have a factory fuel filter and he has an AD-200. Shouldnt be getting any FRP codes with that unless the pump isnt working. It could also be the injectors returning too much fuel, or a bad FPRV.

Is your lift pump working and what pressure is it set at? There are a few different codes for low rail pressure and a couple more that can set limp mode. It helps to know the exact code when possible.
No, those fittings are not a band-aid for low FRP. They are made to increase flow when running larger injectors and bigger/dual pumps.

try replacing you Fuel pressure relief valve, if your showing a p0087 code I think it is for low fuel rail pressure, once it pops its more likely to pop again at higher fuel pressures. I replaced mine and I don't get my code anymore, I got mine from alligator perf for like $35 I think, cant remember.
