Isx 870 fuel pressure

[Kiko]

Thanks for the info again Rawze. I’m still not 100% that it’s the gear pump. I’m at about 80% right now. I know the air bleed valve will put fuel back to return side hose but also if a pressure control valve is leaking it might do the same. When engine is running I’m getting about 240 psi at idle on insight. Would that then rule out pressure control valves or air bleed valve.
