Another Fuel Pump Thread
I'm running out of gas. The fuel pressure starts dropping at about 4000 rpm, down to 42 psi by 5000 on a WOT run, and the AFR starts leaning out at 4000. Full tank. I installed a new stock pump/bucket assy. last summer. With my new engine, I put in a new filter, and a brand new MagnaFuel 4301 inline. I replaced another 4301, it somehow got noisy during the motor job.
Does anybody have a similar set-up? I can't believe that the stock pump or bucket is acting as a restriction.

Its a pressure problem. Put a Bosch 044 pump inline off your main line and you should be fine.
