Fuel pressure is 40pis key on, not running, about 37psi running. Revving ran between 37 and 43psi. No pulsing on idle, steady.

After 30min engine and key off, fuel pressure was still at 28psi in the rail. So I guess I can rule out leaky injectors, although I probably will take them out and clean them anyway while I’m at it.
