People running the cpr or weapon x low side fuel system?
I pretty much copied the cpr set up but with 2 aux pumps.
Is anyone having issues with fuel sloching and uncovering the pick up? I start running into issues at 3/4 of a tank. Under certain conditions I see my fuel pressure drop to nearly nothing. The other day I did a 45mph roll race but with a very abrupt hit (brake boost to ~10psi and then let it rip) and lost all fuel pressure. From a more gentle roll even from a lower speed it flows enough fuel for 18+psi. Seems like the fuel is doing a big flip with the air briefly and uncovering the pick up. I am 99% sure it isn’t any form of vapor lock. I have checked the fuel transfer function and it is constantly pushing fuel to the passenger side as it should. Any ideas? I am thinking about just doing a fuel cell in the drivers rear 1/4 area and feeding the port injection out of that or some kind of a surge tank set up.

I have a similar setup to yours but only with a single Bosch 044. My setup has the setup in the rear/lowest point. I have run the system with the low fuel light on and have not had an issue with fuel pressure. I am doing a surge tank for my port injection, but it is because I'm having an issue with leaking.

It is just a drilled and tapped hole with a fitting threaded into it? No pick up sock or anything like that?

Drilled and taped. I don't have a screen. I do have a pre and post filter though. I'm building a surge tank, but that's to address a issue with leaking.
