I am running a Kieth Eickert pump bottom upgrade from CP Perf on my Gen V 454. I draw through a BIG Wix water separating filter with -8 lines all the way from the pick up to the carb. This pump makes 6.5 psi except at WOT where it drops to 3. I have mixed feelings about it, as the pressure drop is a concern. My motor doesn't lean surge (plugs look fine) and seems to run fine so far. Its a 525sc with a small pulley and intercooler.

Navy,
I can see your concern. As you are not seeing signs of low pressure, I wonder if your FP gauge might be reading low at all pressure levels; 6.5 lbs at idle is also low.

As there seems to be a pressure doubt with the KEPP Gen V pump, maybe they would ship you one to try. If it doesn't hold 5.5+ lbs at WOT, you can return it for credit. If it works out, you agree to buy the second Gen IV pump.
All get to see the results on OSO. Either way, KEPP gets good press for good customer service.

Best to push through a filter as pump design is not to pull but to push. Next, good pumps that I have used personally and can recommend is the Holley marine pump (coast guerd approved) and also the Carters that flow 172 GPH but the Carter is non- marine. I use it now on my 900 HP blown engine.
