NNBS returnless pump setup
Hey, So on my friends 11' FF truck that we turbo'd we built a fuel system in one day with local parts which consisted of two pumps (capable of around 1K hp total) and a vette fuel pressure regulator style filter.
We used AN line with a Y inside the stock gutted bucket to a pass thru an bulkhead fitting running to the vette filter and a line from vette filter back into the stock bucket with another an pass thru. Then output of filter of course to stock rail
Truck on a 575rwhp pull started to run out of fuel.
Its looking like the vette filter is probably the issue with that much volume from the pumps so we are going to put a universal aftermarket regulator in place of the filter.
I will be needing to also do a fuel system on my 07 and looking around on the forum theres alot of ways I see you guys doing fuel setups and most are pretty expensive and complex.
Am I missing something or will the twin in take pumps with universal regulator not work? Seems far simpler than all the other ways ive seen on here.
Is that going to be an issue with the FPCM also? Hotwire kit is probably a good idea.

Also suggestions on holes/no holes in stock bucket with a return line feeding the bucket. Is there chance of running bucket dry? we put 2 holes in his and not sure if that would benefit or hurt the situation.

I think the issue with these trucks is the FPCM, unfortunately. It seems like you need to keep the OEM fuel system intact 100% to keep the CEL off. THEN, do a 2nd intank pump that Y's in and it operated off of a hobbs switch or similar so it it activated when you get into boost.
I don't think a hot wire kit matters on these trucks because they are controlled by the FPCM; from what I understand anyway...
I think the fuel system is going to be the limiting factor for my Escalade once I get the cam and LSA blower on. If I pulley down and add meth, I am going to need to add a 2nd pump. **** sucks for sure.

i have a 2013 f 150 and just recently discovered the hassle of having (FPCM) fuel pump control module. it sits under the bed of truck right above spare tire and im not certified but from my understanding the PCM monitors engine performance and communicates with fpcm to determine how many volts should be pushed to actual fuel pump

This is how I did my walbro 450 in my return style setup. I gutted the whole bottom and cut two big openings at the front and the back at the bottom of the bucket. I also made a bracket so the pump sits at the very bottom of the tank. I haven't got it to 1/4 tank yet to see if that helps with the pickup issues I was having before. I also have the return line angled away from the bucket to prevent the pump from picking up air.
