Boosted with larger injectors you will get a pretty good pressure drop. I have a fuel return system that is supposed to increase fuel pressure as the boost comes on. After pulling the pump and taking a look I think its just the transfer in the tank not working like it should or I use more fuel then it can transfer and empties out the reservoir. I noticed that again the filter fell off the bottom of the pump so I "engineered it" lol.
When turning on the pump and listening I can hear fuel spraying down as it comes back from the engine, I would imagine that this is aerating the reservoir and further straining the fueling system. Ill upload some pics here now.
