FueLab fuel pressure regulator without regulated return

[thewrubelator]

Hey guys, have an 04 6.0, just put on an Irate Fuel pump (FueLab pump) Running around 80-90psi. I do not have a regulated return yet. I was wondering if it is possible to install a FueLab FPR after the pump to adjust it to stay around 70 until I can get time to instal a RR once I get my move to Cali done. If not, is running that high of pressure going to negativily effect anything?

That much pressure may blow out the injector seals.

80-90psi is a little steep, you may be able to run a fuel pressure regulator right after the pump and return it to anywhere before the pump to get you by for now. I would regulate it for 60-65 psi to be on the safe side.
