Message: [QUOTE="6speedsd, post: 1304590, member: 1242"] I've been fooling with this all day. Swapped on my old cheap FPR, which did the same thing. Rules a bad regulator out. Figured what the hell....lets do a bubble test, just to be safe. Passed that with no bubbles at all. So it's not an injector leaking. With KOEO, as the pump runs it sounds like air bubbles passing through my regulator. (I've sort of thought maybe it's sucking air somewhere). Unhooked the feed line on engine side of HFCM, ran it into a clear jug and cut the key on. Fuel had air in it at first, then clears up until right before the pump shuts off, then gets bubbly again. So, figured I'd rule out anything in tank. Unhooked the feed line on the tank side, ran some hose from the HFCM into a jug of fuel, with the engine side feed still in my other clear jug. Basically bypassing the fuel tank all together. Key on, and it's bubbly through the entire pump on cycle. So, it's sucks air in the HFCM, for some damn reason. Like I said, this one is new to me, I never removed the manifold, so it shouldn't be an issue there. All I can think of is maybe the o-ring on the filter itself is nicked or something. Either that or the one on the pump itself. Gonna put a new filter in there and see what happens. If this whole ordeal is because of a filter o-ring I might lose what's left of my sanity!
